I would think that if the bus holds about 57 people, if you divide that by, say 4 (as in 4 in each family/party), that would be 15 groups. I doubt they would all be going to the same resort. Even if they were split between 2 resorts that's still only 7 in each line, since only one person needs to check in. And I have heard that if there is a largish group going to one resort, they call the resort before they get there, so they can get more CM's on the front desk area. Hopefully that's how it will work in 15 days!!
