OMG, 17 has now turned to 28!
The long story is my husband, brother in law, and BIL's future fiancee (it's happening on the trip!) were going on a 4 day Dream cruise. SIL is from Canada and wanted to spend more than 4 days in Florida is she was flying from the opposite side of the continent, so then we decided to do
MNSSHP, a day at Epcot and a day Harry POtter Worls. The my husband realized we would be there over Food and Wine and wanted to stay even more days, to which I said anything over a week is just too long for me to be away from our youngest. So my husband in all his wisdom (insert sarcasm here) invited his parents and brother and sister still living at home to WDW and that way our kids can come too and they can go home with Grandma and Grandpa when we go one the cruise. So Now it's a week at WDW, 4 day cruise and NASA and IOA and dinner at V&A after the cruise
Then my MIL just went ahead and invited all the other siblings of my husband's who are married with their own families to come too (a very sweetly said that my husband and I were paying-umm, no). So that's where the 17 came from.
My MIL also invited her sister and her kids and grandkids, so now we are up to 28.
I'm trying to just roll with it and ignore the feeling like my vacation has been hijacked by my MIL. The way I'm telling myself to feel is that this first week wasn't origionally going to be happening anyway, so even with all these people, it's still gravy. We had planned on a 4 day trip, and now it's two weeks, and I get the to both take my children to WDW AND have a week's vacation without them.
