Here's my two cents.
I got married last year we had some pretty high maintenance personalities in the mix! Here's how we remained sane and ENJOYED our special day!
A.) There is not one gameplan in the world that will please everyone. PERIOD! It's impossible.
B.) I think brides & grooms worry WAY to much about their guests/families. This is ALL about you and your spouse. It's the one day of your lives where it's 100% ok to be 100% selfish!
C.) Selfish friends and family will find a way to get offended, hurt, etc by your plans and/or the details of the event. Their immaturity warrents no concern. Expect it, but try not to care about it.
D.) Do what makes YOU happy. If you wish to be alone for the remainder of the trip then do it! If you want to hang with a smaller exclusive group of guests, then do that! Don't give a second thought or worry about what your guests want. You choose. Your choices should always be the final word for this event.
E.) Don't drive yourself nuts attempting to plan your guest's trips. Refer them to a fee-free disney travel agency who can handle those headaches for you. Small World Vacations is great agency for that... and they won't charge anyone a dime.
