...mmm..Vickster, I've been there once to often and have consequentially started saying no. I also have a daughter who hates being in the car, gets car sick, throws up all over herself in it, wont sleep, and therefore car journeys are a torture for both her and me. Life is much much too short to (willfully) do things that make you and your child unhappy. If it were only you going up for the celebration that would be another thing..the celebration's success would purely be a function of your presence..but it seems there are others to keep the elders entertained? Call me a selfish so and so but I'd say: dont go, buy the tickets + chuck in a bottle of bubbly while you're at it (heck you'll be saving X times more than that by not going) and send them your heartfelt commiserations for your non-attendance. Yes, I am a bad bad person... ;-) Plus, if you do feel guilty, you'll be having to spend another weekend with them in the not to distant future by the sounds of things..so you can celebrate it with them again, then.
