i just booked three rooms for Beach club for June but to get the room quickly i didnt add the other names to each room, just one person per room...can i do that online or should i just call
You cannot adjust the list of names using the on-line reservation system without canceling the entire reservation and starting anew. You can adjust the occupant list by either calling MS or going on-line and sending an email to MS.
I recently added guests via an email to MS. It was easy. The names were the kind you have to spell and I didn't have a lot of time to spend on the phone, plus the request was far from urgent since the reservation is many months away. I liked the email option.
