The 2 hotel reservations - cash + points — are for one continuos stay and was made end of July, beginning of August. Some time after Marriott issues new SPG numbers to all accounts a note appeared in my account announcing a new reservation number had issued for an existing reservation.
I did not think anything of tye number change until earlier today when I emailed the hotel with our room request for our 10 day stay. The hotel wrote back immediately saying they have us booked for only 5 nights and that they show our second (points) reservation was cancelled. The hotel was very accommodating and after receiving the confirmations immediately reinstated our reservation
This does not appear to be the hotel’s fault. I suspect either inaccurate and/or confusing information was sent to properties. If we had not checked on the reservation today it’s likely we would have arrived at the resort planning to stay 10 nights but could be accommodated for only 5 nights.
