Ok, I just learned about this so I'm scrambling go catch up. I read a ton already, but not all 300 pages of this thread. So I'm hoping for some advice.

Marriott: 352K points
SPG: 63K points
As I understand it, I can convert the SPG at 3:1 which would giv eme a total of 541,000 potential points.

We don't know where we want to go yet, or when. Is our best strategy to just make an educated guess as to where and when, and then to book the highest category 7 night option? IN this case, a Tier 4-5 Cert, and attach it to a Tier 5 hotel?

Also, regarding miles. I have exactly the same number of United miles as American right now. Is it better to select United miles for the bonus or Alaskan Airlines??

Much appreciated any advice. Trying to figure this out quick before it all goes poof!
