I think it all depends where you're going - my best holiday foodwise was Northern India as I found the food, almost exclusively vegetarian, delicious but light and satisfying at the same time. The times I have put on the most weight have been when it's all inclusive, just brings out the piggy in me and I tend to stuff myself.

Also find Stateside quite tough, as there are so many superb seafood restaurants with enormous portions! The desserts, which I don't usually bother with, are, in the words of my granddaughter in Texas, AWESOME (and very calorific!) Saying that I have recently been away, just in Scotland, and indulged disgracefully in huge full Scottish breakfasts complete with black pudding and tattie scones, fish and chips most lunch times and three course dinners most nights washed down with plenty of wine and of course a wee dram nightcap! I have gained a few pounds granted, but had a great time and have complete faith I will start losing again soon, thanks to 5.2! If you don't have many holidays and really want to enjoy it I would just enjoy the food experiences and get back on track when you get home

otherwise, just stick to the 5.2 or 6.1 and enjoy your holiday!
