For the OP - When we did our tour, we had educated ourselves a good bit before hand. When we went to the kiosk, the CM told us the tour would take about 90 mins to 2 hours. We explained that we would like to JUST see the models and talk to the guide about how many points we would like and where. We did our tour in less than an hour and didn't bother with the free ice cream, lol! Because we were educated on the perks and such of
DVC and the prices and incentives, it helped our guide to just do what we asked for. Maybe this would be helpful for you to do as well. Good luck on your visit and if you decide to buy any points. It wouldn't hurt to ask about resales while you're there so that you know your options there as well. That is the one thing we didn't know about - being able to buy at places other than SSR or AKV through Disney. But all in all we're happy with our SSR purchase!
