This probably sounds like a stupid idea but why dont you save all of them until christmas before you open it up lol. You probably will have around 450 spins by christmas so even if you dont get Rolex out of those spins, I think you will still get decent amount of RP out of those spins.

Another idea would be to open them in the next 20 days because the lambo winner will be drawn 21 days from today so you might be able to snatch few golden tickets from the spins before the it was drawn. Small chances obivously but its way better than having none of it
