Heads up that Raiwasa is trying to walk back these bookings already. I was fortunate (or perhaps unfortunate depending on how this shakes out) to book 10 nights for 4 people (2 people per room). At time of booking it was not possible to book more than 4 - it does appear that it is now, so they have already modified things. I was contacted by the resort initially with information regarding the resort, possible upgrades - things of that nature - and confirming the full booking - no mention of any additional fees, seemed clear everything was good.
They contacted me again today indicating that what I had booked only covered 2 people and I would owe the price difference for any additional people beyond this. No cost was disclosed at time of booking, I paid in full with points. There really was no ambiguity when booking, but it does appear I will need to battle for what I booked unfortunately. Will be interested to hear others experience as I don't see how they can back out of honoring these really but it looks like they are going to try.
