boston classpass

I absolutely looove solidcore, and I used to be able to book pretty easily through class pass, whatever classes I wanted were typically available. there’s 6 studios in the boston area but I can’t get into any classes! I noticed this getting worse around solidays and I thought that I would be able to go regularly again- not the case. I am a nurse so I know I would be able to get a decent discount if I got a membership, but financially I don’t think I can afford it :( any advice on how to get in on class pass??
