Hi, So I have booked an apartment for 5 people but currently we only have 3 confirmed going including myself. For various reasons who aren't sure who the other 2 will be for perhaps another month. I am worried about not being able to get 5 lift passes if I wait too long. I tried buying 5 Epic Passes but they require name and birthday for each pass. How can i ensure I get lift passes for the 5 days we are there even though I won't know all the guests until perhaps another month from now?
