I would be very upset if I tried to leave IG only to be told I had to go to the front of Epcot for a bus, then walk to the front of Epcot and get there just in time for the weather to clear enough that they have started the gondolas up again and cancelled the buses, so I get directed to the back of the park again. You could end up bounced back and forth many times on the typical summer day. It would make more sense to run a bus going to all three gondola resorts from a location near IG if weather causes the gondola to shut down, since all three resorts are close together geographically. If I were told to walk to the front of Epcot, I would probably go hang out at BC until the weather cleared enough for the gondolas to open.
