I am on WW and with the timing of my August trip, I may be on maintenence or at goal when we go to WDW. So I'm going to be careful not to mess that up (all those months of work at WW!)
My plan is to eat a normal breakfast in the room, and eat a proper WW lunch (salad, plain grilled chicken, etc.) I will also try to eat fruit. Dinner, I plan on splurging... but to be honest, I do not think I can physically eat a lot anymore, so I should be okay there. My main splurges will be dinner, dessert at dinner and alcohol.
Good Luck!
