I'm an 18 stone male, and while I don't know my measurements I imagine most females would be more chesty than I am, with chest size being the restricting factor on most retaints. I struggle with colossus and vortex restraints closing at all, with Samurai pretty snug too. I'd guess you might have to skip these, but other than that you should be fine.
I'm not so sure about the wheelchair restrictions, I know some rides have evacuation and access issues, I'd hope these would very posted on their website?
