Sorry about bumping an old thread but I was stupid and booked something through VacationsByMarriott thinking it was run by Marriott. I should have noticed when it asked me for my Marriott number.

Well for my combo flight cost 365. I originally booked it separately for 408. Thinking I will save 43 bucks and get 5000 points compared to the 2000 + 1000(plat) points I would normally get for 200 dollar rooms.

Next time I'm going to do the vacation by marriott and book only 1 night and then book the rest of the night separately. As far as I can tell, I still get United Miles for the flight part. I'll lose out on 1 night and get 5k Marriott points for it.
