OP again - I talked to her last night and she wasn't actually fishing for a thank you or more money, but reassurance that she did enough during the vacation. She was feeling bad (or insecure?) that she and her bf spent a lot of time away from the family, so her hinting around for "thank you's" (which is the way I interpreted her comments) were just hinting around making sure we were happy with the way the vacation went.
I'm so relieved. We have a great relationship and like I said before, she's always been comfortable saying "no" when we've asked her before if she couldn't or didn't want to and when we invited her, she really did act like she was psyched about going - I feel so close to her - I mean, this trip really did start out as her spending Christmas with us and evolved into this vacation. She assured me it was like she expected and they had a great time (and thanked me for the trip) but also added that when they got home, bf and she started talking about whether WE were okay with the arrangement - that they were concerned that they "disappeared" almost every night without checking with us if we needed her. And she started worrying that I was unhappy with that. I assured her that it was what our agreement was and part of the gift (that they get every evening free and on us). Oh, and someone asked - yes, we paid her regular wages which would have been paid whether she came with us or not.
It wasn't meant to be a free vacation to her. It was a working vacation with quite a bit of free time and the chance to bring her BF along as well. While I think that most stuff should have been covered for her anyways, if I chose to go out on my own for dinner each night, and out to clubs etc I wouldn't expect the family to pay for that. That would be out of pocket. If I didn't want to pay for my own dinner, then I would eat with the family as that WOULD be covered.
It's like when you go to college. The cafeteria is included in the food you pay for each semester, the pizza place down the street is not. OP was very nice about paying for these for both nanny and her BF. OP made it clear to her nanny that this was a Christmas gift to her. If the nanny did not want that as a Christmas gift, then she could have turned it down. She could have said I will cover my own extras, I would rather have a bonus instead to do with as I please. I don't think OP would have minded that option. There is more of a chance of nanny and BF taking advantage of no bill to them and splurging instead of nanny paying and deciding to keep costs low so she doesn't have to fork over as much.
This poster said it exactly right. we of course assume we'd pay for all expenses as part of her compensation, but not if she wanted to go out and party - That was the extra I was referring to that we think is the "extra" that would normally not be covered, but we covered as part of her Christmas gift.
Anyway, all is good. I assured her that we are extremely happy with the way the vacation went. We appreciated her helping every afternoon with the kids and we were really glad she had such a good time with bf.
