"The best laid plans of mice and men gang oft a-gley." Doing lots of work for a one time big family event sometimes is doomed before it even happens. People drop out at the last minute leaving you holding the bag. Or they show up with extra people. Or they expect you to purchase all the park admission. Or they want you to change the dates because Bobby has Little League practice that week.
Be careful. New members always want to show off their new toys to the rest of the family. And the rest of the family doesn't always appreciate your gesture.
Yes, all of this is true. If you want to host an event like that, you can, but keep in mind all of what the poster above has said. We have owned
DVC for nearly 10 years at both SSR and AKV. In the early years, we would treat my brother and his family to staying at the same time we did in a studio. We all tried staying in a 2BR, once, and that was a disaster. His family didn't want to go to the parks (or I should say his now ex-wife). She didn't like that we let my son drink Propel instead of plain water. It's better than letting him dehydrate in 100 degree weather. I think that she told my niece that I was "stupid". Really. That coming from a woman who doesn't even have a 2 year college degree talking to a board certified physician. Sounds like somebody doesn't actually know what "stupid" means.
I guess maybe I am a little stupid, because I rented 2 studios near each other for them to come the same time as we did the next year. Then ex-SIL got a little greedy, and wanted to know if I would book a room for them a week when we weren't coming. The answer was "No", and I quit inviting them to stay in a room that I booked. My brother and the kids came the next summer, and stayed at a different timeshare, and joined us for activities.
Now, I a contemplating doing another "stupid" move. I have always wanted to stay at a tree house villa, which is too much space for just my family (I had thought about doing it with my brother and his family before my SIL started her weirdness). This time I was going to invite my husband's family, who live in Tampa. So far I haven't done it, because of experiences with my family. No guarantee they would be any better behaved. If I have low enough expectations, namely, people will come and go as they please, not stay the entire time, not want to go to the park, etc, it might just work.
