True. Depends on your luck and property. My biggest scores were 15 nights each at 2 nice beach resorts and 10 nights at now gone Westin Our Luckaya (Bahamas), plus maybe a dozen of over 6 nights stays at a big city property (there I would stay 3-4 times a year for 10 years). Not giving actual names as do not want other plats to flood them and ask for similar treatment
. Many failures as well. But I don't have much experience staying over 5 nights in the same place except my 2 or 3 regular spots. 5 nights upgrades I have had a bunch. But this belongs to a different thread I guess.
