If you haven't made the changes already, something like this in your 'other things to note' and 'guest access' description could help to relieve any confusion. Hope this helps~
============================================================
1~2 guests = 1 room (master) & 1 bath (ensuite?)
3~4 guests = 2 rooms (master + A or B) & 2 baths
5~6 guests = 3 rooms (master + A + B) & 2 baths
* Extra room charge of X amount per room must be paid for use of extra bedroom(s).
Depending on no. of guests, some rooms will not be accessable unless extra room charge is paid in advance.
============================================================
Also, if the reservation is not confirmed then you can send a special offer but if the guest has already paid and they have a confirmed booking, you will have to use the "request money" function for the extra room charge.
