There are not formal and semi-formal nights on the Wonder 3 or 4 night - only the Magic 7-night. When we did the Wonder 4-night, we gave up Parrot Cay and have no regrets. We hit that one for lunch one day, and thoroughly enjoyed the other two for dinner. Palo was great - no regrets about sacrificing Parrot Cay here. I'm sure you will get many different opinions on that one, however!
