I would call them directly. They are great with teachers. When I got there they didn't even ask to see my school ID. The rooms are awesome and the pool is great. The only bad thing was that we couldn't ride the Magical Express. Don't know if that is still the case.
I will have to call. I don't see any discounts for November on the website. . . I wonder if they only come out so far in advance. . .
I am booked at the BWI (40% off PIN), but if I can get a better rate at the S/D I'd probably take it -- they are an equally great location!!
If you call and don't get what you want, make sure you call back closer to the date. I'd be surprised if something w a teacher discount didn't open up for Nov, unless it's Thanksgiving.
