You can call 1-800-800-9100 and set up a time for your trip. They will also send a free video and information packet. You can also schedule onsite- there are DVC kiosks in all resorts ( usually near the check-in area) and in all Theme Parks and at DD. You can also schedule from your room- there will be information proivided at check-in and on the room TV.
DVC will pick you up at your resort for the tour and they have a children's center, so your DD will have plenty to do while you enjoy the tour.
SSR contracts go until January 31, 2054 while all of the others end January 31, 2042. During the tour you will see video of the other resorts and will see the SSR models at the resort. I'd plan on about 90 minutes, but if you don't want to spend that long- just let them know and they can tailor the tour to your needs. If is a fun, informative event with no pressure.
Your Home Resort will determine when you can make a reservation and how much your dues will be each year. At 7 months you can reserve at any resort- based on availability.
Enjoy the tour.
