Nezy,
On the 4-nite, the special Chef's menu is on the fourth nite of the cruise, ( is it the same on the 7 nite???) so that while you are repeating one of the restaurants, you get a completely different menu. Plus, by going to Palo then, you do not have to give up any of the other three restaurants! I hear that this is the very most popular night to get reservations at Palo, and that you have to be in line early to get in.
I am planning on Palo for that 4th nite, since the special Chef's menu seems to have gotten mixed, at best, reviews. But a brand new post here today says that they are now changing that menu!
Had I done a poll on this, I would have listed :
1. Lumiere's(Magic) / Tritons (Wonder)
2. Animators Palette
3. Parrot Cay
4. Chef's Menu night
