I'm trying to book points reservations for next summer and can't find point redemptions available for rooms that can accommodate 6 people. I've tried both Marriott and IHG. Redemptions are available for smaller rooms, but not larger ones and there is plenty of capacity at the hotels.
Is there a way to book larger suites with points?
Most suites only officially fit 4 people so just do a search for one person and if you feel you can fit 6 people in the room go for it.
Hyatt lets you book suites with points (again not officially big enough for 6 people) with a minimum 3 night stay
SPG will let you book suites with points as well by calling (obviously in both cases you will have to use extra points)
Ive seen some marriots that allow you to book a standard room and pay a small upgrade fee per night to get a suite as well so you can look into that too.
Finally Airbnb is best when travelling with 6 people
But again I believe the root of your problem is that you are searching for 6 people
