I think you have to look closely at how you want to use your points. 25 points at AKL is going to get you like two nights a year in a studio or four nights in a studio every other year. It's not much. I don't really advise buying up a bunch of small contracts at different properties because you won't be able to combine the points until the seven month window.
There's a pretty good premium on small contract points- $10-20/point sometimes. So it's not a very economical option either.
I'm looking for a small contract at HH, but only because I plan on only going every other year, because the points are fairly inexpensive, and because I ONLY plan on using those points at HHI. Otherwise, I'd only really look for small contract add-ons for properties and use years I already own (ie, I own 300 points at AKL with February use year, so if I add more AKL with February use year, it just increases the size of my contract and I can use all of those points at AKL at the 11 month mark).
Yes indeed one trip every 2 years is the plan.
