All of Phipps is wheelchair-friendly (elevators as well) with the exception of one room (which I believe is called the Stove Room) and really wasn't decorated for the holiday. The tropical forest is accessible, but the path down to the lower level is an incline, although I've seen strollers and wagons on it and they didn't seem to have a problem. At the bottom, there is an elevator back up to the conservatory level. Wear shoes that are a little "grippy" though, the humidity level and waterfall splashing can make the paths a little slippery at times.
