Yes, you can alternate your bookings to maximize the 3 free nights each. No it's not bad etiquette. You'll need to talk to the hotel upon arrival, though, to see if they'll let you stay in the same room since you'll be checking out/checking in each day.
Cheers.
I'd like to add that the best is to make sure that you pay and close the bill every day so that nothing can be messed up.
