I have 2 stays this year and another 4 days booked at Residence Inn by Marriott New York central park this week total of 6 and only 2000 reward plus this upcoming stay of..... My question is once this calendar year is over will my points and the 6 stays go away and make us start all over next year? Is this true for all hotel chains?
Your stays/nights go away and you start at zero next year toward earning Silver or higher status (since you are below the 15 level for silver and thus won't have any 'rollover' nights). Currently Marriott points don't expire, except for the catch all provision, that at any time, Marriott can end the program or change the rules.
I'll let others chime in on the other chains
From Marriott Rewards FAQ
Do Marriott Rewards points expire?
As long as you make a paid stay at a Marriott hotel every 24 months, your account and points remain active. Otherwise, your points may expire.
From Hilton Honors Fact Sheet
Hilton HHonors points do not expire as long as members remain active in the program. To keep an account active, members can stay at one of Hilton Worldwide's hotels, or earn or redeem HHonors points within 12 months.
I know that is a fact at Hilton as I didn't stay there within a year and a couple of months later checked in and tried to get credit and I didn't exist. So guess what I rarely stay at Hilton anymore as I think it is a very dumb policy. I stay occasionally at Hyatt and I always get welcome back even if I have had no actively in a couple of years. Don't now how strict Marriott is but I doubt if they are
