We have a "room" only reservation for a campsite from 11/5-11/19. Our friends have a free dining reservation at CSR starting on the 14th, and they're flying down. How possible is it to have them stay at our campsite for a day or two before their CSR trip? There would be 10 of us total, so we wouldn't be over the capacity for the site. Would they have to be listed on our reservation (and potentially pay extra adult fees) for all 14 nights? They'd like to use Magical Express, but they don't need access to their park tickets or dining plan while they're staying with us.
