My wife and I have been accumulating SPG points so we can do a big 10 year anniversary trip to a location that has those villas on the water. We have 100k starpoints saved up. In looking at SPG, these are all category 7 hotels at SPG. I would like to make use of the Marriott Points+Miles program, but I want to do it right. If I move over my starpoints to marriott, then I should get the 7 night certificate in a category 7 hotel, and then book the hotel between 8/2 and 8/18, right? Or, should I be getting a higher category hotel certificate?
