I've been on both sides of the coin--the person imposed on by relatives and the one left behind! It bothers me when relatives do things like stop by unannounced and such. As for the latter, here is the story: BIL and SIL went on a Disney trip and invited other siblings and cousins in the family, including us, to go with them. We decided to come along, then DH thought, since all the siblings and grandkids were going, to invite his mom and dad, too, and pay for his parents himself. They were aging and DH wanted to take his mom (who is all of the grandkids' grandma) to Disney before she passed away since she had never been and has always wanted to. Well, SIL wasn't happy to hear Grandma and Grandpa were coming (it's her DH's and my DH's parents, not hers). We were surprised because we figured since they invited everybody else to join them, it would be no big deal to have the parents go to. And everybody was paying for themselves and only we were paying for mom and dad, so it wasn't a money issue. They didn't want them there. To make a long story short, at Disney, after breakfast, they left us (DH and I, our kids and Grandpa and Grandma) on our own and went ahead. Didn't spend any time with us the whole trip. Perhaps they felt that since they were old, they wouldn't keep up. But the whole trip? Would it be too much to spend a dinner or a little bit of time with us, since they invited us to come along in the first place. When we saw them staking a spot for the parade later, they didn't even invite us to sit with them. We truly felt unwanted just because we had mom and dad with us. I thought of Lilo and Stitch's motto--"Ohana, nobody gets left behind."

Well, my DH's mom did pass away a couple of years later, and despite it all, my DH feels good that he took his parents to Disney and that he and our kids spent that magical time with her before it was too late...
I hope things work out for your trip and for everyone involved...
