I know this is probably stupid to ask, but if I buy the 5 consecutive days for the price of 2, do I have to actually use them for 5 days in a row, or they just expire the 5th day after it's been used for the first time? We're only planning on going 2 days, 2 1/2 tops, but this looks like the cheapest way for us to go. However, we don't have a plan in place and probably won't use them on "consecutive days". Just want to know what the deal is before I buy them. Thanks!
