I will have back to back reservations (vacation followed the next day by work - so different hotels in same city) in November. The first stay will qualify me for the first level of the current mega bonus. It is my understanding that you have to wait to get an invite for the new "unlocked" bonus and then register before you can start working towards that. Is this true? My travel work really dried up 4th quarter, so I'm wondering if I need to fudge and stay at a Hilton or something for a day or two in between to give myself time to register for the "unlocked" bonus whatever it might be.
