If you want some alone time (but no hurt feelings) I would make it very clear that you are Disney vets, and as such, will want some time to cruise at a different pace than they will. They may resist and say, oh but that's ok -- we will just follow you! This is a response also born of fear -- where will we go! Whatever will we do? Here's where you lend an early helping hand -- help them set up an agenda for those days. Help them plan it, asking them what they like, the "must-dos", etc. Map out an appropriate day's path for them. Explain again that these are things they will really want to do, but that you, having been there, done that, do not need to do, but you surely would feel AWFUL if they missed them on YOUR account! Then, fully knowing what THEIR schedule will be, you can plan how much you want your schedules to overlap (if at all!) For example, if they plan a full day of fun at EPCOT, perhaps you cruise MGM, then say, Oh, you'll be dining at EPOCT -- we love it for dinner -- we will meet you and stick around for Illuminations! They will enjoy the peace that comes with knowing they have a "plan" and that you will occasionally cross paths during that plan!
We ALWAYS travel with family, and it has been my experience that the very BEST trips always allow for time apart. That way, everyone sees what they want to. Plus, we get more "stories" that way to share over dinner -- if we all go to the same places, what would we discuss? Last trip, we had lots of "forks in the road" where we went separate ways. One day most of our crew went to TL; I took DD to a princess bfast and Mk for girly gal fun. That night, I took our teenage nieces into MK for E-ride night. Another day dh and I took our crew to BW to pool hop while BIL, SIL and their fam went to MK. Another time 2/3 went to MK, another 3rd went to MGM, and we all met at Epcot for dinner! We ahd lots of fun discussing over dinner our exploits for the day, and each group felt they had done what they wanted that day! They key is to never make anyone feel that "your path" was in some way more magical, better-planned or somehow superior than the plan the other crew took. Just enjoy everyone's happiness, and for those whose plans might have had snags (like my poor dh's decision to stay in MK with BIL and our ds to ride BTMRR and SpalshMtn -- only to have it thunder, lightening, and DUMP water for the next 2 hrs and close both rides while they stood in it and learned what it's really like to be SpongeBob SoggyPants firsthand), find a way to laugh and make a memory out of it! <a href='http://www.smileycentral.com/?partner=ZSzeb008' target='_blank'><img src='http://smileys.smileycentral.com/cat/16/16_6_2.gif' alt='Thunderstorms' border=0></a> <a href='http://www.smileycentral.com/?partner=ZSzeb008' target='_blank'><img src='http://smileys.smileycentral.com/cat/10/10_1_12.gif' alt='Smiley Shell' border=0></a>
