We also always have the Gerber Graduates fruit Juice snacks, they are easy for a baby your age to diguest. Last summer we brought some fruit snacks from Costco with us on vaction and she ate a ton, turns out her poor tummy couldn't break them down and she threw them all up for the next 2 hours. Not fun (any time or on vaction.)
We plan to get out mostly for lunch and dinner, maybe one or 2 breakfests. We like to eat snacks in the room and occaional lunch if we are in the mood at the villa. One nice things is if you have leftovers you can actually take them home and eat them later if you feel like it.
