Best BKK airport lounges with paid access that dont require a membership or that specific airlines ticket

I have a late evening departing flight at 7:30 but hotel checkout is at 12. I'd rather get to airport early and chill than trying to run around to squeeze in an extra half day of activities.

So which lounges do you recommend that allow paid access without a membership or ticket to that specific airline?

I have plenty of Air Asia points to redeem lounge access on Cathay who I'm flying with...but because my membership/card status isn't high enough with them they wont let me redeem my miles for lounge access which is BS.

So I'm looking for other paid options. Thanks.
