Aimeth,
This trip sounds like great fun, our trip to Vegas one week ago was a celebration , starting off 2008 with a new perspective..my younger brother and his wife and my older sister and her husband were all with us. 2007 was not good to us for many reasons. I can relate to your frustration with others jumping on to the band wagon to go to Disney. How old is your son??? Who wants to go with you??
Anyway it may be good to vent your feelings, but if not just approach it before hand decide to have a good time anyway and make it what you can, suck up the fun. Make it clear you want a few days by yourselves or evenings.. When in Vegas we met at dinner with our family members,then stuck together for the evening leaving the day open to ourselves..sometimes I can only handle a few hours with my sister, she seems to think I need her Advice because she's older, I am 62, and capable, believe me!! so we just make an excuse to wander off..be creative, make it work..SET LIMITS ON WHEN YOUR WITH OTHERS, MAKE IT CLEAR,I had so many speeches from people who nothing about what we were experiencing, suggestions, blah blah blah,,,I say this is your trip, enjoy it to the fullest, and let the rest go!!!!Have an outstanding time,,,,I love Disney, hope to do it soon ourselves!!!
