I want to summarize my concerns about the gondola at Pop Century here:
1. Without AC, it will be too hot. I only go to WDW in the summer, and it's always 95 by the afternoon, and I always travel back to the hotel in the afternoon to rest before heading back. But even in the morning, it is still rather hot being crammed in a bubble with 8 people all creating body heat and nothing but vents for cooling. The buses, in comparison, has powerful air conditioning.
2. The gondola will take too long from Pop to go to the 2 parks, I'm guessing about 15 minutes to HS and 22 minutes to Epcot, counting the transfer at Caribbean Beach and the stop at Rivera. (5 minutes each section, 5 minutes transfer, 2 minute stop at Rivera.) The buses currently take only 10 minutes.
3. The transfer is too crowded. The transfer station at Caribbean beach will be servicing 3 large hotels going to 2 parks all together. That's 6 bus stops full worth of people. Say if I want to go from Caribbean beach to HS, I will being joining the line not just from people from my own hotel but two others all come pouring into my gondola station. Normally, CB's different buildings have separate bus stops. Now they have to all walk or take their internal bus to get to the gondola station, fight the mob from Pop and AofA, and finally get to HS. That will take a lot longer than the bus. The Rivera won't have the problem going to Epcot, but they still need to transfer for HS. The gondola may reduce wait time, or it may extend it, depending on how fast it can load and unload.
4. Pop will raise the price to help pay for the gondola.
I can, of course, move to All Stars, but Pop has been my favorite resort for years, and it is such a shame that I can't stay there because of the gondola. Some people ask why worry about it now, when the gondola is still a year away? Because I have to plan my vacation a year ahead, so I need to decide soon if I want to change to All Stars.
Of course, one can hope that the gondola won't be that hot, and it won't take that long, and the transfer won't be too crowded, and the prices won't hike, and the overall experience will be an improvement over the buses.
