Initially I was on the Wonder - partly because it would complete my Grand Slam but mostly because I wouldn't be losing a day at sea to Star Wars, which I do not like. But the more I thought about it, I don't really like San Juan that much and I've been there and St Maarten before (whereas the Western is all new to me), I am not a fan of Triton's menu (I don't do duck or fish and that severely limited the gluten-free options without being "that person" demanding that they bend over backwards and make stuff totally not on the menu to accommodate me) and the more I heard about Tiana's and how supper club it sounds (I detest supper clubs) I decided to change and get a verandah on the Fantasy so I can have an outside refuge on the lost-to-me sea day.
Then I started remembering how much I love sea days and the Eastern gives me more of those. And figured I could just suck it up and tolerate Triton's, request Tiana's for night one and do Palo then and the other Tiana's night. Enjoy the sea days, hit a beach in San Juan, figure out what to do in St Maarten (or elsewhere as it looks like St Maarten may be questionable based on it disappearing from an itinerary yesterday and there only being one shore excursion listed). But when I did the math, it was as I posted earlier - I have a balcony for less than $500 more than I could get an OV on the Wonder. So I'm staying with the Fantasy.
