I am renting points for the first time at Jambo house and have a std. view.I was just wondering whether it is ever possible to pay for a sav.view difference at check in like you can for AKL rooms?
Not possible. You get what you reserved unless there is a problem with the villa you reserved and there is nothing left in that same category. Usually no complimentary upgrades, either.
Points reservations can never be upgraded using cash. Even if there was a room available, it would go against the member's points and since you are not the member, no changes to the reservation are allowed.
