I need help from the ticket gurus. We will be at Universal Oct 21 -24. Our best deal for tickets appears to be the 5 days for the price of 2 deal. There will be four of us & we will be using only 2 or 3 days of the 5 as we are leaving early Sunday. Is there any rule against selling the remaining 2-3 days to someone else? I figure that if I can sell them for a fair price both sides will be happy. Is this ok to do? Thanks.
