What you want is the fastpasse cards they hand out to the people with e-tickets, they have no expiry date on them so can be used for as many visits as you like. The new system at DLP is that you can only hold one fast pass at a time when it used to be as many as you wanted.
Just got back last week and happen to have 6 of the afore mentioned passes

made for a very relaxing time not having to queue too much
