Remember when going to Orlando you will never get to see or do everything. If you tried then your vacation could be ruined as you'd be so tired. Have each person pick out something they would like to do. Use the resort services when booking things to do or see. We had them do our reservations when at Disney.
Watch out for all the little booths that offer discounts on tickets. They are for doing a timeshare and the 90 minute talk can last for over three hours. We did one and what a mistake. Ended up walking out as they were rude and pushy. If you don't mind this, then try one as some do have good deals.
The main thing to remember is have fun and take it easy. Disney World is packed all the time so crowds are bad and some lines may be long. Have patience.
