Changing hotels frequently serves two purposes: 1. Maximize elite stay credit in hotel loyalty programs where elite status requires a lower number of stays compared to nights (e.g. Starwood Preferred Guest Platinum and Hyatt Gold Passport Diamond = 25 stays or 50 nights; Hilton HHonors Diamond = 28 stays or 60 nights). 2. Maximize hotel promotions that are based on number of hotel stays. “Mattress Runs” is the concept of changing hotels frequently rather than staying at a single hotel on an extended stay in order to accelerate stay credit for elite status or promotion credit. Since SPG requires 25 stays or 50 nights for SPG Platinum elite, it is possible to stay 40 nights in hotels and still not earn Platinum if you only have 15 to 20 hotel stays. Mattress runs allow you to boost your hotel stay count without adding more hotel nights. Important to remember: you cannot stay at the same hotel on consecutive nights and get multiple stay credit. Even if you check out and check back in on a different reservation, all hotel programs count consecutive nights at the SAME hotel as one stay. Here is an example of a strategy I have done many times over the years to maximize stays. Assume I need 3 nights in a hotel in San Francisco. I spend Thursday night at Westin Market Street since it is the cheapest rate for a weekday. Then I go to Le Meridien for Friday night when rates are low. On Saturday night I go back to Westin Market Street. My 3 nights in San Francisco earn 3 elite qualifying stays. As long as I change hotel properties, I can stay in Starwood Hotels on consecutive nights and earn a unique stay credit for each hotel. This strategy is useful for Hyatt, Hilton and Starwood where fewer stays than nights are required to earn elite status. Marriott only counts nights for elite qualification so mattress runs in Marriott Rewards is for the purpose of promotions like the recurring MegaBonus offer for a free night after two stays. Mattress runs are particularly useful during “Stays Count Double” promotions that SPG and Hyatt have offered most years in the past few years. Mattress running is a lucrative strategy during free night promotions when a free night is earned after every two or three stays. Hyatt Gold Passport, SPG, Best Western Rewards, Choice Privileges, Carlson goldpoints plus, Hilton HHonors, and Marriott Rewards have all offered this type of promotion in the past year.
