I always have a difficult time choosing between the 2. BUT, I have to lean just a bit toward the Swan because it is smaller and more intimate.
As far as the quiet goes, that really depends on room location at either. You do have to go a lot further though for a room at the end of a wing in the Dolphin. But, you do have conveniences like Tubbi's and the awesome restaurant FRESH. Of course, these are both a courtyard walk away from the Swan.
Actually convention goers stay at both resorts, but the bigger conventions are at the Dolphin but I've never had any problem with that at either resort.
The rooms at the Swan have 2 sinks as opposed to a vanity area and 1 sink at the Dolphin. The rooms at the Swan have 2 queens as opposed to 2 double beds at the Dolphin. All rooms at the Swan are renovated and almost all rooms at the Dolphin are renovated. Kings are available at both resorts.
The bottom line is the amentities are pretty much the same. If you stay in the far east wing in the Dolphin it's almost the same walk to Tubbi's even if you're staying at the Swan (except if it's raining LOL)!!
It took us more than 5 Swan stays to finally try the Dolphin because I was hesitant that we wouldn't like it as much and honestly I'm glad we did, we were NOT in the least dissappointed with that choice. So, if you feel like trying something new you should be fine, if you'd feel more comfortable staying at the Swan by all means stay there (sorry hope I was helpful...LOL!!)
