Ditto on everything in this post!! This pretty much sums up the entire list of benefits, which is why we stay more than a month at a time when we visit (longest was five weeks @ the Dolphin in a suite). They are amazing, and an astoundingly great deal when compared with any of the Disney Mods (which close their pools by 10pm, etc). There are too many perks associated with these properties, not associated with the Disney props. Here's just a few more notes to add:
*While you may not be permitted to charge park items back to your folio/room, you may have them delivered from any park!
*Walking back to your hotel after watching illuminations is indeed MAGICAL!

Grabbing an ice-cream along the way? Priceless! ^_^
*The beds are phenomenal...heavenly, to be exact!
*Kids straight "A" club (and if they only have one or two A's? It's STILL ALL GOOD!)...where your kids may bring their report card to the desk, receive another card--which entitles them to a FREE ice cream at the fountain!!
*Interior corridors (vs. moderates with exterior hallways), in nice air-conditioned comfortable surroundings. Less mosquitoes, less chance of lightning striking you (seriously here), and less chance of sweating through your fresh new attire before you even arrive at your destination.
*Some of the BEST restaurants on all of the property are in these resorts! The BEST steakhouse, (by far), along with other incredible chef-inspired eateries make it a fabulous place to be centered.
*The GROTTO Pool remains our #1 of any on property, including the Beach club! It is truly an oasis.
*The boats...the bus...the leisure paths, all lead to the magical world of DISNEY. You may rent a swan paddleboat, and just enjoy a lap or two around the lake.
The SPA is top-rated, and my favorite above the GF! It's the same one over at the PBH, and I've loved it for years now. You can not go wrong on ANY treatment in this place. Give it a try, and you may even use SPG points for discounts or complete treatments! ^_^
Which leads me to the last point...the Starwood Preferred Guest Program. Consistently leading the pack in customer service and satisfaction for ANY hotel frequent guest program. The points accumulated can be used for upgrades, free nights, treatments, dining certificates, etc. The Disney program (using their visa) does not even come close (IMHO), and I have oodles of points/dollars from their cards as well.
*I just prefer the SPG program. This program is currently offering a special bonus of up to 12,000 points for summer stays through August 31, 2007 (2,000 for two stays, 6000 for four stays, and 12000 for 6 stays!). Visit SPG.com/promo by July 15 to register for this promotion. That's a heck of a great bonus for staying at properties we already Love and/or planned to visit!

After each subsequent visit to the Dolphin, we almost felt as if WE should be the ones giving them some kind of bonus ("them" = the powers that BE in corporate positions), for operating/maintaining such a stellar property! After all, memorable stays are not something which merely happen by chance/luck.
So, to us...the Dolphin & Swan make perfect sense when planning a WDW trip. We do in fact LOVE many of the other deluxe Disney props, and still manage to split our stays to include them on each trip. But, for some reason, we all prefer the Dolphin over all the rest.
In the end, it's all a matter of personal preference. If you choose to stay at the Dolphin, I surely hope it's everything you dream of...and much, much more~! Enjoy your summer and plans!
