We are talking about taking two vacations this year, one to New England in the Summer and a DVC trip in November/December. My husband wants to invite his mother on both trips. We have taken my parents and MIL on two DVC trips in the past two years. In the past, we have also taken MIL on two trips to New England. However, I told him to pick one or the other trip to invite her or pick somewhere we could drive so it would be cheaper. I have always bought her plane ticket and if we take her to New England versus DVC, the rooms will be more expensive. I just think it is too much to take her on both vacations and pay for most of her expenses which would equate to about 7 weeks of daycare. I also spend every Saturday (50% of my free time) with my MIL. I do not want to spend all my vacation with her and pay for her to go on two nice trips. We could afford to pay for her to go on both trips but we would have to watch our money and it would be equal to 7 weeks of daycare. My husband's argument for taking her is she is on a fixed income (so are we, actually we get a 1% raise but our health insurance costs will increase more than that). Am I being unreasonable to ask him to pick one vacation or the other to take her?
