I set up a mini scavenger hunt for my FI to make up for the fact that his bachelor party was cancelled. He got a massage for his back (which is always bothering him), then met up with his good friend for lunch, then to the dog park with their pups (one of the big things they have in common), then the dogs were brought to their pet hotel where the guys swam with them (!). Then they met up with me and the friend's wife for a limo ride to a local little ski lodge where we had a lovely dinner. The next day, the guys taught us how to ski, and then we went and got couple's spa treatments (separately). We went to a couple local vineyards and then back home.
Not quite a bachelor party, but I think he had a good time
Thanks so much for the suggestions!!!
