Yes, I agree with Nelie that there is a good chance that at this point a lot of the weight will "clear up" in short order once you get back to your normal routine. At least a certain portion of it isn't going to be extra fat in storage, but water weight, "bulk" in your system, etc. Of course, you shouldn't use that as a reason to not fight your hardest to hold back any gain possible- portion control and balancing higher cal meals with lower ones are probably some of your best friends right now (along with the exercise).
It's kind of like a military battle in that sometimes we are on the offensive, and the goal is to make as much progress (safely) as possible. Sometimes we are on the defensive, and the goal becomes keeping the damage to a minimum and making sure that we are ready to re-group as quickly as possible. But it isn't necessary to "win" every moment in order to be victorious at the end.
I say you're doing great! Exercising while on vacation is certainly above and beyond the call of duty- and I'd put you up for promotion if I had the power!
