This was what I got from the manager of the RR condo
Here is the answer from RR with regards to the pier. The pass can be picked up at the security hut upon entry to RR.
Here is the exact text of the rule change:
For access to the pier for diving or other use there is a charge of $2.00 dollars per person or $38 pesos person.
You need to purchase these tickets in advance at the security gate at the entrance to the complex.
If you do not purchase a ticket you will not be able to access the pier.
This change has been put in place by the hotel to assist in the costs of maintaining the pier in good operating condition.
If your diving with DIVE HOUSE OR DIVE PALANCAR you do not need to purchase a ticket as they have concessions in the hotel.
For ALL other dive companies you need to purchase a ticket unless they provide you with a ticket in advance.
