Part of me is excited about the new transportation option, the gondolas will be like a new attraction just as the monorail is (to me). We go in January so the heat usually isn't an issue during that time of year if no a/c.
My one major concerned is all the additional guests/foot traffic that will be using the international gateway to enter and exit Epcot. If that entrance isn't expanded the existing entrance will become very crowded. I'm hoping that the exec's at WDW will expand that entrance to allow for the added traffic. I'm sure they will or it will be a major bottle neck and there will be many very unhappy guests, myself included... That entrance is one of the big benefits to staying in that area of WDW. I guess we will have to wait an see but I have confidence in the WDW execs that they will do the right thing.

I stayed at the Swan in the 90's and it was walk, boat or Tram as the options at that time to enter Epcot even back then. If they closed IG then it would be adding brand new bus service. Also, no bus service from thise resorts to DHS. It's walking or the boats. If the boats are down for some reason like there were a few weeks afo then they add bus service but it is not normally offered.
