RCI will send a reservation request with a specific section (and sometimes unit), but Vistana still reserves the right to change that. Make sure you back up this request with a Diamond Lane form 3-4 days prior to check-in. I'm assuming your friends had a banked week or something similar because that has to go through RCI ? Or perhaps they purchased one of RCI's promo get-a-ways ?
The elevators are indeed in the newer sections (Lakes and Cascades), but I'm suprised they confirm that with skyauction ? The "sleep 8" doesn't necessarily mean it's a new section, only that it's a 2 bedroom villa. Only the Falls section is a "sleeps 6" and the one bedroom lock-outs are "sleep 4". When is your check-in date ? I'll be very suprised if it's more than 60 days out, because then they're taking the newer sections that people own and giving it to bidders on skyauction ? Technically, as owners, we have until 60 days prior to make ressies at our "home" resort. We can make them at less than 60 days also, but we risk not getting anything because they open that inventory to general public. Perhaps these skyauction bids are on the builders percentage of what they own ? I know with DVC, Disney reserves a certain amount (is it 2%) to set aside for cash ressies.
