By the way I found out the with the gay days tickets it says valid between
9-30-08 to 10-14-08 but you can use your first day of any pass on 10-14-08 and can use the remainder of the ticket till 10-18-08 if it is a 5 day pass.
I'm pretty sure you would have to pay the difference between the price you paid for the discount ticket and the gate price of the 6 day hopper - which is $209. You would probably be better off calling DLR and asking if they would offer a discount 6-day hopper for the gaydays convention.
