We did the 4 night Wonder in 200o and it was a tease so just did the 7 night Eastern. Ports differ-7 night easter-St Maarten, St Thomas and
Castaway Cay. The rest of the time is at sea. If you like a ship that really moves the 7 day eastern does the entire time at sea compared to one night of speed on the 4 day with the rest of the time meandring at sea.
7 night has a formal night and a semiformal night the rest of the time was casual. We really enjoyed the Formal and semiformal because the atrium just seemed to be all a buzz with excitement, moreso than on the other nights. Lobster tail offered on semiformal night.
Palo's has a High Tea although despite being # 34 I was unable to book it. Also Champagne bruch which is out of this world!
As far a children, I will have to leave that up to someone else to contribute. My child is 25!
