Tropicana hands down for me! I LOVE IT THERE!!! My family loves it there and its definately our #1 choice. I would suggest though calling and asking for a 3rd floor room. That way there is no one over top of you to stomp etc. Not that I heard any noise anyway.
Pros: Clean, Friendly Staff, Nice Pool, quiet, super duper close to the park, they have a convenience store attached which is fantastic, free continental breakfast which my whole family thought wasnt that bad as we found it better then other hotels we have stayed at, restaurants all around you, the bus stop is right infront so if you are taking a day tour through gray line the bus picks you up right outside the hotel, and another thing is that they are more then willing to hold your luggage for you so if you arrive early they will be more then happy to hold onto your luggage, and if you want information on day tours or info on things to do in the area the staff are so knowledgeable and are more then happy to go out of their way to make calls for transportation, getting you tickets etc.
Cons: The beds a bit hard, but after a day of walking, playing, laughing, screaming and having the time of your life, your gonna be wiped out anyway and the mattress feels like a cloud.
