Attending a club again this weekend! wanting to try MF/MF soft swap or parallel play. Advice?

Hey everyone,
My wife and I are attending a sex club for fifth time this weekend. To say we are a mix of incredibly excited is an understatement!
We have talked a lot about our comfort levels and want to take things slow. If the vibe is right and we meet the right couple, we are hoping to explore one of two scenarios:
MF/MF Soft Swap: Interacting with another couple for kissing, touching, or oral, but keeping full intercourse strictly off the table for our first time.
Parallel Play: Being in the same bed or immediate space with another couple where my wife and I play with each other, and they play with each other. We love the idea of the shared energy and watching, while keeping our physical boundaries completely to ourselves.
Since this is our absolute first time in a club environment, we want to make sure we handle it right.
How do we best communicate these specific boundaries to another couple without sounding rigid?
If you started out with soft swap or parallel play, how did it go for you?
Any tips for managing the nerves once we actually walk through the front door?
Thanks in advance for any advice or reassurance you can give us!
