That may be personally true for you, but it's not true for actual Park attendance at WDW. As of 2014, MK is far and away the leader at 19.3 million, but EPCOT is strongly in second at 14.4 million, with AK and DHS more or less tied for third (10.4 vs 10.3) with AK generally squeaking out a win year after year. But with Pandora opening, and DHS very cut down, I could easily see people who are on 3 or 4 day stays who might have done DHS doing AK instead. That could be a shift from a few hundred thousand to over a million. And DHS with 1 million fewer visitors in a year, is 2800 fewer people per day. That's going to feel like a much emptier park, even with the smaller footprint. More importantly, it's a significant number shifting into AK. Personally, with the size of AK, I think it can handle it, but with only 2 new rides wait times for the few popular attractions will go up.
