I need some opinions

Existing white card member with 230 SSR points. We use them as sleep around points and it has worked well. Our normal trip is a ~ one week total split stay in a studio or 1BR, so we take the best option available at 7 months. Parks style is to hop between MK/EP/HS with a mid day break. My favorite resort is Riviera which of course we are locked out of.
230 points is proving to be not quite enough. Sitting on $13k cash that is burning a hole in my pocket. Debt isn’t an option for me. Looking at 3 add on options:
1) 50 pts direct at Riviera or Poly. Starts me towards the blue card and full flexibility. I would envision a blue card within 5-10 years. I don’t need it today as we don’t have time for AP
2) 100 pts Resale at Riviera. Restrictions generally don’t concern me as we could bank/borrow
3) 100pts Resale at another sleep around type resort, maybe AKV. Let’s me do what I’m already doing but with more points in the war chest, plus a bit of a 11 month window
Thanks for your input!
