Cake eating WAW in MLC and EA part 2

[CABBR]

PDT,

We have been going to a cottage on a lake, which is about a day's drive for us for more than 20 years. My W inherited the cottage with her brother, with whom I get along with well. We go there every year for our primary summer vacation. It's a beautiful spot and there is another cottage next door owned by my SIL who can be difficult.

If I want to take the kids to the lake, there is absolutely nothing my W can do about it. I can take the kids for summer vacation and avoid my toxic SILs or do something else entirely. My W would probably arrive later and bring them home.
My sense is to do something else, even though it will cost a lot more money, which I'm not going to have before too long.
