The details for Olympus
"Enjoy unlimited complimentary access to domestic and international airport lounges for primary and Add on card members. Enjoy annually up to 20 complimentary lounge visits for accompanying guests."

I am assuming it means that I will be able to continue using priority pass at domestic lounges without a fee and will be allowed 20 complimentary guest visits
Any idea if guests will be allowed on add on cards (I understand that the total pool will still be 20 only)?
