I have a Standard Priority Pass membership. Does anyone know when using Priority Pass, can one enter, leave, and then re-enter a lounge without paying again? Is there a consistent policy about this at all airline lounges?

My situation is that we have a three plus hour layover at PDX during the lunchtime. My wife and I were hoping to enter either the Red Carpet Room or the WorldClub, then leave and have lunch, and then return, maybe even with our lunch.

If anyone has any information, please let me know.

Thank you very much in advance.
