I'm always interested in a new addition to the
DVC resort family even though I know I wouldn't necessarily purchase points at most of them. I have enough points but a shortage of years at this point so realistically, I'm not likely to buy any more no matter where they build another resort. However, Rivieria sounds very interesting to me and I'm looking forward to staying there when it opens. Gondolas don't cause me any unease and if they turn out to be a relatively quick and easy method of transportation to the parks, I think they'll be well received. That and the somewhat spectacular views from the resort that are severely lacking at the other Epcot resorts, will make them popular enough IMO.
As far as the IG goes, as with all things Disney, if it gets more crowded, it gets more crowded. We'll just have to deal.
