I can re-post my reviews from a few years back.. Keep in mind: for the Hilton I've only stayed there once (2013), same with the Sheraton (2015), Holiday Inn has usually been my favored hotel, as an IHG member I get a parking discount which is a big cost saving for me. Hope all this info helps, even seeing as it's now March I'm guessing a lot of the hotels are quite booked by now...
For 2013, I had a room in the Hilton. It was great having the air conditioned walkway connecting right to the convention center, and the lobby hangouts were a lot of fun too. Room wise, ours faced the baseball stadium. That was a sweet bonus. Couldn't see the game, just top of the grandstands we weren't up high enough. The room size was fair enough, my twin sized inflat-a-bed fit snugly between the window bed and the window. Very nice bathrooms from what I recall. Not much for amenities in the room: coffee maker, iron + board was about it. The TV ran PMVs the whole weekend too. I didn't get much time to check them out, just randomly when we'd be in the room and turn it on to watch random pone. My biggest gripe about the Hilton: the elevators. >_< I swear there was one, or two, maybe even three, elevator(s) that never worked the whole weekend. The wait times got a bit tedious sometimes. Did not matter waiting on the ground floor or the 2nd floor (sky walk level). There does not appear to be any stair access that connects the 2nd floor to the 3rd floors and up, or at least I never found them. Also parking I found a tad pricey, but advertised at 7' clearance it easily fit my 2010 F150. The stalls were nice and wide too! I did book a cheap "throw away" motel for Thursday night in 2013. The Ramada Inn Pikesville. It served its purpose, also my one roommate was able to park his car free there for the weekend and we just used my truck to get to downtown. But also learned just to stick in downtown for the whole weekend.
For 2014, and 2016, I got a room at the Holiday Inn. We "lucked out" as it was on the 2nd or 3rd floor.. Right in front of the stairs to boot!! (I prefer walking to elevators, just personal preference to get some exercise) Elevator wise, the hotel is rather old (60's?) and the elevators are wee bit 'tight' for space, and ride quality too. So having those stairs and a lower level saved soooo much time. The Holiday Inn room was just huge! Again I had my inflat-a-bed between the window bed and the window, and I think I easily had feet on each side, not just inches as with the Hilton.. More amenities such as a fridge (yay!), I think a microwave, and the usual coffee maker, iron + board, etc... The bathroom set up in the Holiday Inn is as such; the toilet and shower are in a separate room, the sink/counter are open to the rest of the hotel room. At least, it was for this room when I was there in 2014. This would be a sweet setup but there was no bathroom fan! (constant gripe for me and hotels) Still, at least one person could take a shower while another was washing up. I was nervous about height restrictions with my F150 and their underground (advertised at a measly 6' exact), but they also offer open air parking on top of the garage so that was great. Also, to gain access to the lobby/hotel common areas after 10/11PM you need a key card. I found it a lot more secure that way, if you like that sort of thing. Fairly fast walk to and from the convention center. You are crossing over Howard/Pratt to get to it though. Pratt is fairly busy street, at a lot of times of the day. Oh, also breakfast in their dining room got pretty pricey, I suppose that's true for most hotel foods, I really liked the Subway for their breakfast subs (kitty corner of the convention center at Pratt/Howard) In 2016 I had a room higher up and more in the middle of the hotel. It was a bit different than the one from 2014. More of a "regular room" I'd call it.. Still had room for the inflat-a-bed, but back to inches between the window bed and window not feet. The bathroom was more of a traditional bathroom, everything inside the room instead of the sink out in the room portion.
For 2015, my friend booked the Sheraton. I found the coolest part of the Sheraton was that every time I came to the lobby, there was a elevator waiting with its doors open. So sweet! Parking wise, it's the most ginormous garage I've been in yet, I think 6 or 7, maybe 8 floors? I sweated a lot, advertised as 6'2", my 2010 F150 just fit with no real big issues than the antenna pinging off low hanging conduit pipes. The spaces however, are really narrow for trucks like mine. Hotel room wise, it was also really tight! It was both my Inflat-a-bed and a roll away bed from the hotel. Very, very, very tight. The Roll away just squeezed between both beds, and my Inflat-a-bed was hogging the "hallway" from the front door and beside the bathroom. Bathroom wise, it looked nice, but shower head wasn't all too great in our room. :\ Come to think of it, the shower head in the Holiday Inn wasn't all too great either. Again, no fan in the Sheraton bathroom too. >..< grr Room amenities: coffee maker, iron and board, and a safe. No fridge . The Sheraton is connected to the convention center via an uncovered sky bridge. It's fun to get to the doors in the "mid level" (200 level) of the convention center. Or, you can walk behind the 300 level rooms to the Otterbein lobby too! There is one small road to cross to get to that lobby, and there is a crosswalk button for a safe crossing, or just make sure there's no traffic and dart across >..> <..< .... Small caveat: I learned late Sunday night, there is a gate that closes, guessing for "week nights" and must include Sunday nights too.
For 2019, I have a friend who's getting a room at the Hyatt Regency. He wants the SkyBridge access. So, I'm eager to see what these rooms will be like.... Guessing for the price he's already quoted me it won't be a harbor view but that's alright. Parking for the truck looks like 2nd best off the Hilton at a height of 6'7".
