15 nights is like nothing for me to get..
50 nights is pretty easy..
Im more looking for a longer amount of time on vacation to use points on, rather than just a few very expensive nights..
I would want like 2 weeks in a modest but decent hotel with points, not like 2 nights in some incredibly fancy place..
Im an outdoors type.. I don’t sit around in my rooms.. If anything I sit around outside in the patio areas and be sociable with others..
A hotel is really just a place to shower and sleep to me, it just can’t be in disrepair and dirty..
Well, that leaves out Wyndham-filthiest places I've ever stayed, well besides some of the Thai countryside places on hotels.com.
If 50 nights is easy, I'd strongly suggest going for Titanium with Marriott, as that will be enough if done before 4/27 to get there, plus some, on their double-double promo. Also, currently they have a 125k credit card bonus, so you could easily earn enough points for a couple weeks or more in a mid or lower category.
Of course, we travel a little differently, as we like a nice (or great) room, though we do like to spend time outdoors, preferably with a swim-up feature, as we had at the JW Marriott Khao Lak, or next week's beachfront villa with private pool at the Renaissance Koh Samui. As with all things, it depends on what you like.
