I booked every tour through the tour department and told them which discounts I might be eligible for and it worked out fine. You can call the member services number and go to the new dining option to book tours. I found that out last week when I made dining ADRs. The CM said that they also do the tour booking. If you have a Disney Visa also ask if it is good for the safari for a discount. Some of the ones I have booked the discount has been different depending on the tour.
