If you want something really, really bad...

AHAHA, and there I was thinking all these nature walks would have compensated for cruise food. ;)

But really, when mamoru22 and I spent our vacation in this Mexico resort a few years back it was the same: In the morning you were waiting for the breakfast buffet to open, then you read a book at the pool, waiting for the lunch buffet to open, then there was an afternoon snack bar, and in the evening the dinner buffet. So much food, so little exercise!
