I just recieved my first ever pin code and i have some questions about how it works. If i wait to use the code closer to when it is up will i have less chance of getting the resort/date i want? Do they only have so many rooms/dates/resorts open per pin code offer? Can i book it in my name and pay with a different credit card? It came to my email but only has my family's last name and address listed does that mean anyone in my household can use it? Or only me?
