It was actually my choice to stay home, same thing happened last summer when the family went to the cape.
I actually enjoy it like this. I hate taking more than a couple days off in any given week... I don't need a full week off. In the 2 years I have been with my company I think I have used a grand total of 5 or 6 vacation days. One of those was for a wedding and one was for my brothers graduation.
Plus I get the house to myself for the week. Take a couple days off, have a long weekend, then a short week. I get to take over the garage and set up the welder, torches, etc w no worries about getting a "clean that up, I want the garage tonight" demand from the parents. Get to relax around the house/pool with some quiet rather than the kids siblings screaming and running around. It's quite relaxing
So yeah, I get the house to myself that week and then the folks are going to the cape again the week of July 4th so I get the house again. Can't wait. I may go visit on the cape for a day or two but haven't decided that one yet.
