There are no specific details on what may occur IF FD is released.
In the past, all resort levels got the regular DP. Last year was also that way until FD was extended through December...the extended dates had the values get the QSDP while mods & deluxes received the regular DP. There is a lot of speculation that this year will have it tiered as well...values with QSDP, mods & deluxes with regular DP. The FD offer is rumored to be released on May 3rd, so we just have to wait and see.
Bear in mind, though, that if you're looking for an end of October date, you may not see FD heading your way. It typically only goes from mid-August to the very beginning of October to accomodate the value season. Last year they did extend it, but there isn't a guarantee they'd do the same this year. Right now we're only hearing about a possible FD promo for the typical mid-August to early October time frame.
