Access to Mera lounge at Cancun

I understand that UC passengers are allowed access to this lounge,how is access granted?, are you given a pass at check in?. Many thanks. y)

From memory it's a voucher at check. Lounge quite small and was very busy with loud with Americans doing shots

You will be given a lounge invite at the check in desk, although we had to ask for ours. They will not let a Gold card holder take a guest in at this lounge either. It's poor uninviting with no windows and very limited snacks and drinks.

Your not missing nothing, very basic. I prefer grab a cold one in bubba gumps and watch Tom Hanks at his very best
