you guys just need to know where to eat, this is why reservations are so important
i've only had a few bad meals there, one of the worst was at the floridian....and i am very picky....
the only downside to the dolphin/swan is i don't think they have regular bus service from the parks, but i could be wrong.
imo instead of paying to park ($11?)at the different parks throughout the day (if you have a rental), then park at epcot, it's usually opened the latest so there'll be no worry of getting to your car too late, from epcot you can get to pretty much anywhere on property with the bus system/monorail.
if you don't rent a car a cab should be pretty cheap (again if there's no buses), just get to epocot, to get to another park from epocot jump on the monorail and goto the grand floridian to catch a bus to get to any of the other parks (buses got from resort to park only, not park to park), the floridian has dedicated buses which will go strait to their destination iirc.
since you have free hotel accommodations then you should easily come out ahead financially if you don't spend frivolously, AAA has killer discounts, may be better to get your park hoppers through them.....but check around.
wifey and i have been to disney 20+ times in the past 7 months with our annual passes.....
