I also did SBD a few years ago and I definitely would not deprive yourself on a holiday. If you're already into phase 2, your body probably isn't craving sugar/bad carbs anymore so just having a taste or two of a "forbidden" food will probably satisfy you and not send you back to square one with the diet.
