You initially lost me. I believed you can book upto 10 rooms on awards at a time. PB is just a lower redemption rate Award night. You enter the number of rooms on initial search screen, no different to booking and making reservations for Paid Nights.

1) I now kind of see where you might be coming for, as clicking
RESERVATIONS->POINTS BREAKS -> Continent to search shows 'Number of rooms prefilled as '1' and not an edittable field
BUT after SEARCH returns result, you can click CHANGE on returned seach results and modify number of rooms.
'best available' or
2)If you know City/Hotel is in PB's, you can simply use standard search, either
'Best Available' or 'Reward Nights' in RATE PREFERENCE pulldown selection. Either way Award Nights if available are shown, along with points/per/night needed, whethe full say 25K or 5K PB rates per night.


That is rooms not nights, so you could eg book 2rooms for 7nights, a total of 14nights, as long as your IHG account has a high enough points balance. Looks based on dummy booking you need book a)1x Room for NN nights b)Duplicated Award Booking when offered after making initial award booking

However PB's showing does not mean hotel will have PB room rate left available for every night in the current PB period OR even 2nights every night.

If eg 7nights 1rooms dd/mm - dd/mm says no availability, I'd recommend checking 1rooms on PB, 1 night at a time, to see which nights are the issue.

HMMMM ... Just tried Arnhem Holland, 2rooms one night, when I set preferred to Awards not best available I got following Pop-Up text box
(Even Changed Search, showing 2adults, 2 rooms, when selecting Room on points, shows 1 room)

Reward Nights
When redeeming points for a Reward Night, you may only book one room at a time.
Once you complete your Reward Night reservation you will be given the option to duplicate this reservation.
