The
DVC tour may be arranged at any of the kiosks located in all of the resorts, Theme Parks and DD. You can also call from your room to schedule. they will pick you up (and bring you back afterwards) and child care is provided (if you need it).
All of the tours are at SSR and will take about 90 minutes- but if you have time concerns, just let them know and they will work with your schedule. It is a fun tour.
As noted, you should also be aware that all resorts are available thru resale and you may be able to save a few $$$ using that route. regardless, I'd suggest taking the tour, as it is most informative , entertaining and very low key/low pressure.
Enjoy your trip!
