Darn good promo IMO, considering that people are saying this is going to be the "sellout summer" and Hilton doesn't likely don't have much incremental lift to gain in terms of filling rooms. Especially interesting that it's an escalating bonus on longer stays, given that many folks will naturally be taking their first extended vacation trips in a while. So I'm curious about the logic from a marketing perspective, but certainly not complaining as a customer!
