How do you do the reservation account swap nightly? Doyu make the entire reservation under one name, and just checkout/in, switching the rewards account each time? Do I need to make a bunch of different reservations in alternating accounts/days?

As said in a previous post, I am staying sun-thurs nights for the next 3 weeks in Raleigh and am trying to maximize AA miles. Next week I am alternating b/w Hampton and Wingate. Getting HH Surpass intro promo of 2500 bonus HH per stay and doing this promo from wingate.

The week of the 25th, I have yet to make reservations, but I am probably gonna stay entirely at wingate to max out the promo. There is also a Hyatt and Comfort Suites in the vicinity. I would like to stay at the Hyatt to use this promo, but the rooms are a little pricey for my hotel budget. Room budget is $90 max before tax which wingate and hampton meet. Would the Hyatt Costco certs still make the Hyatt promo valid? They would bring the cost to within reason. Best suggestions?
