I like the Swan, because I like that it's smaller, and quicker to get around. The general consensus is that families, for the most part, prefer the Dolphin, because it's a little more lively, and because of its close proximity to the grotto and kiddie pool, the arcade, laundry, and the quick service food option (Picabu's).
Room-wise, the Swan's standard rooms are slightly bigger than the Dolphin's. The Swan has two queen beds; the Dolphin double beds. But they seem to be a bit larger than your standard double bed, so the difference between the two bed sizes is not that great. Also, the Swan has a Hollywood bath...a second sink/vanity in the bathroom itself, along with a sink/vanity outside the bathroom. The Dolphin only has the one sink/vanity, outside the bathroom.
Of course, the rooms differences won't really matter if you're in a suite...
Re: rope drop, for the most part, when we've headed to Epcot early, the CMs have allowed the crowds to enter through International Gateway, walk through England and Canada in WS, and into the rose gardens that are along the pathway between WS and FW. It might take you a little bit longer to get to Test Track, but you'll only be seconds behind the crowds heading to Soarin'. Again, that has been my experience, when we travel in September...it could be different for people who go at other times of the year.
The walk to Epcot is 15-20 mins, tops. Then again, I walk slow, LOL.
Here's the dish on the pools, which I shamelessly cut and pasted from the first page of this thread..
There are 5 pools:
~ a grotto pool with tropical waterfall and water slide
~ two lap pools, one closer to the Dolphin, the other nearer to the Swan
~ a spring pool
~ a kiddie pool
There are also four whirlpools. Always good to know!
There are two poolside restaurants, which can be found near the Dolphin and Swan lap pools, respectively.
Activities include:
~ Water volleyball
~ Electric boat rentals
~ Staff supervised pool games
~ Two sand volleyball courts
~ Basketball hoops
~ Ping Pong Tables

Oh...and did I mention the hammocks?
They really are great properties. I can't believe it took me as long as it did to realize that. But now I'm hooked!
