RENT THE SECOND CAR!!! Lesson learned in one very long, frustrating, wonderful trip with me, DD (6), Dsis and BIL and niece (1.5), BIL's mother, father, niece (9) and nephew (12). We would not have been able to survive without the second vehicle. True, we wouldn't have fit in one vehicle, but still...travelling with just Dsis, BIL, and nieces (now two of 'em), we find the 2nd car a necessity. REMIND THE SMOKERS THEY ARE GOING TO A (mostly) NON-SMOKING PLACE. And gently point out that it's really unhealthy for you and your kids to hang out in the smoking area. Perhaps plan ahead for smoke breaks...they can hang in the smoking area while you ride somehting they have no interest in. TAKE INTO ACCOUNT EVERYONE'S EATING HABITS!!! In our extended family trip above, the most fighting came about over meals. Sis's plan was big b'fast, small lunch around 2ish, dinner after we left the parks for the evening OR small b'fast, big sit down lunch, small, snacky supper. Everyone thought this was good, but BIL's parents needed their sit-down dinner at 5 or they were intolerable. 12yo nephew ate ALL the time- waiting for counter service is like waiting for smokers, plus younger kids wanted snacks too which meant nobody was hungry for when the meals were planned, except for my DSis, who became cranky when nobody wanted to eat as scheduled! BE GENTLY CONSIDERATE WITH SUGGESTIONS!!! Let them think you are recommending they join you at lunch so they can sleep in and not have to get up at the crack of dawn on their vacation- when in reality this is YOUR time with YOUR family to do what YOU want! Finally REMEMBER that there is no way, regardless of how strictly you follow a touring plan, that you will see everything! Your first encounter with a single character (to say nothing of Snow White with all 7 dwarves) will throw the day's schedule to H-E- double toothpicks and back! A big part of Disney is the *being there*, soaking up the atmosphere and savoring the moment. If you love it as much as I do, you'll definitely go back again, even though right now you probably think this is a "once in a lifetime" trip. (And if you hate it, it won't matter if you saw everything or not!)
