Due to insufficient total points, I used 3 different rewards program to book 1 night each for a 3 night consecutive stay at a hotel.
For example:
Crown Hotel on 01/07 - 03/07
Citi rewards (01/07)
Flybuys (02/07)
Qantas FF (03/07)
All under same name/person.
Has anyone done this before? If so, how was the experience? I fear that they will force me to check in and out 3 times and allocate me 3 different rooms throughout my stay.
Your fears are correct, this can happen, or you could get the same room.
You'll cause confusion as the staff will see the room up for a 'end of stay clean' but you'll have your stuff in there!
