Well, Wyndham points are available cheap resale and are flexible, but you'd need a lot of points to stay once a month just "straight booked for a week", and if you did manage to grab just a weekend or the like, you'd run out of housekeeping credits so it'd just add cost buying those.
I think you might be well placed to consider a "Timeshare Lite" like the timeshare traveler says on Youtube, and look into the Homewood Suites/Residence Inns hotels that come with a kitchen and a bit more of a studio suite kind of layout. If you liked Hilton ones, the Surpass card might be worth it if you can churn spend through it - you'd get extra benefits, a free night each year and build points for more free nights or just discounts on stays. And they have a Home2 Suites off of I-95 about 8 miles away for 36,000 pts a night Aug 22-23 as an example this year. (That's a pretty low points value). It's $116 a night cash with HHonors. That's a pretty low cash rate too.
At the very least, you could give it a try pretty easily without buying into anything, and if you did decide to go into HHonors the Surpass card is $150 a year but like I said, you get gold membership, FNR if you churn enough spend and points to bring down the cost a bit each year.
As someone else said - Orlando has a bunch of TS, some a little closer in Kissimmee but that still looks like 1.5 hrs away so not ideal. What Wyndhams have you been staying in?
