I have 2 waitlists in place since April for an October trip for 3 nights. I have also been stalking the reservation system and the first night came available today so I booked it. Now, I only need 2 nights of that waitlist instead of 3. Question is if I modify it just for 2 nights do I go "back in the line" for my waitlist or will my April WL original date remain? Thanks!
