Well, this was my original plan...My sister's family, our mom and my family were going to stay in 3 rooms at AS's with me and my sister splitting the cost in half since some of our children would be sleeping in grandma's room. Then I got hip to renting DVC points from an owner and thought for just $200 more for the week, we could all stay at OKW Grand Villa and I was going to offer to pay an extra $100 so that me and my husband could get the master suite. I thought that would be fair since I was making all the arrangements anyway.
Well...my sister's family has since bowed out of the whole vacation plan so that my niece can have a Sweet 16 party. (She obviously doesn't know that Disney is WAY better than a party, but that's not my call.) So we're staying with a 2 bedroom villa and I'm still paying more that our original plan, but we'll make up for it in savings on our meal expenses.
Sooooo, I would suggest that maybe you offer to pay a little more of the cost so you can get dibs on the jacuzzi!
