I was originally registered for MGF62 5000 every 3rd stay up to 25000.

This didn’t really fit in well with my stay pattern for upcoming stays so I phoned and they changed it to the MGF63 35,000 for 20 nights without any problems.

When the promotion ends or on completion of the 20th night I’ve got to phone back to have the points credited though as the online tracker still shows the original promotion
