Janet,
Resort hopping is a very popular activity for Walt Disney World vacationers. Unfortunately it is one that I have never really understood. For me, the moving is a hassle mid-vacation that takes time away from getting to a park. Also, it keeps me from feeling like I have a home-away-from-home during my stay. I would not do it, but that is just me.
If I were to do it, it would be to combine the luxury of a deluxe stay with the affordability of a moderate/value stay. Keeping costs down, but still getting a few days of higher end accommodations. While I love the theming of the moderate resorts, none are so alluring that I would make the move just to try them out.
So this is probably not the advice you were seeking, but I would recommend staying put. If, however, I were so compelled to want to try out a second moderate resort during my stay, I would go to
Port Orleans French Quarter. For two adults this is a great setting, a bit quieter than the nearby Riverside, and with boat access to Downtown Disney for some nighttime dining, shopping, and fun!
Have a magical vacation!
