Here's my 2 cent review.
I was very happy with the Inn at The Ballpark. Well worth the $58. The hotel is located just a couple of block away from Minute Maid Park, the home of the Houston Astros. The hotel has a baseball them to it, but not in a tacky way. We didn't spend much time in the lobby so I don't have much to say about that. It looked nice from what little I saw.
Our room was nice. Hardwood floors in both the entrance and bathroom. Plaid carpeting in the rest of the room. Our 5th floor room had two windows, one looking out into the lobby and the other with a partial view of downtown and the lower part of the hotel roof. There are some paintings in the room that continue the baseball theme of the hotel.
The only downer for me was the shower, not as much pressure as I normally like and the shower head was much too low for my taste. Anyone over 6 foot would have to bend to get their head wet. I was sort of surprised to see this from a new hotel (opened Jan 1st, 2004).
The staff was nice and courteous. We got the king/non-smoking room we had requested. I would highly recommend this hotel to anyone, especially those wanting to stay close to the ballpark. It's also only about 7 blocks away from the Toyota Center arena.
IMPORTANT NOTE: Inn at the Ballpark is nice, but for the first time in my priceliniing career around Texas I've been told that to "upgrade" from a single King to two Double beds would be an extra $30 per night. I realize of course that the hotel is completely within its rights to do so, but personally I consider that to be dishonorable. If they want more money from Priceline sales, they should raise their minimum bid. (Of course part of the problem is Priceline's inability or unwillingness to nail down more precise booking details in their basic setup, but that's probably immutable at this point.)
Anyway the hotel is OK, in a banal theme-hotel sense. It's fairly new and the room amenities and physical construction are above par. Of course the on-site restaurants are so-so (Landry's owns the property, and their business model seems to be offering hyped-up ambiance and mediocre food at hilariously inflated prices), but the people have all been very nice. Nice (if small) fitness room with enough towels to sop up Lake Michigan. Free (wired) Internet in rooms, and DVD players (important for families).
