Hi, Tammy,
I went to House for my surgery and my husband and I (and our daughter, who was in grad school at the time, spent several nights with us as well) stayed at Seton Hall for almost the entire duration. We had an early morning flight back to New Jersey on a Saturday, so we left Seton Friday afternoon and went to one of the LAX hotels (I think it was the Marriott) for the last night (this enabled us to turn in our rental car at the hotel on Friday and catch the hotel's airport shuttle rather than navigate the LA freeways the morning of the flight).
I was very content staying at Seton the whole time -- we had a car, so did not feel at all "confined" there -- and I was very comfortable knowing that House Ear was across the street and St. Vincent's was an even closer walk (via basement tunnel or short walk outside). It's not luxurious by any means, but certainly adequate. I know there are some people on the forum who did go to LA hotels after release from the hospital (House provides a list of relatively close hotels), so I hope they'll join this discussion.
I do think that having the rental car made a big difference -- I didn't really have any post-surgery issues, so we were able to get out and about on a regular basis (except, obviously, the days I was in the hospital).
Best wishes as your plans develop.
