I love staying at the various WDW resorts beyond the
DVC resorts. Some trips we stay totally at a DVC resort but many times we change resorts. We always stay at only Disney resorts/on property. I would gladly try Swan/Dolphin but am always able to get a better deal at a WDW resort. I often plan trips that purposely include a Fri and Sat night(s) just so we can stay in the other resorts. WDW has some really fantastic resorts and we find it a lot of fun to experience them for a few days each trip.
Where I book depends on many factors. Who will be in the traveling trip, what type of trip is it: business/pleasure or just pleasure, the budget etc. Once I determine this, then I shop around for the best rates in whichever resort category I have decided on. I am always able to get some type of discount from the various ones I am eligible for. The pt savings by avoiding Fri and Sat nights easily translates into at least one and many times 2 more trips per year--which is well worth it; plus we really enjoy our little mini trips at the other resorts.
If you plan and pack accordingly, moving from one Disney resort to another is a piece of cake. We love it. Now we are a group of all adults but we have been changing Disney resorts since the kids were preschoolers and it has never been a hassle.
My next 2 WDW trips are ironically, either BWV and
Disney cruise or totally all at a DVC resort, but for trip after that we will be staying AKL concierge--enjoying the wonderful lounge offerings, relaxing at the pool, taking in the amazing atmosphere, restaurants, etc., of this resort AND going on the Early Morning Safari, before we move to our BWV villa. Ahhhhhhhhhhh, sounds great to us!
