Well, Punta Langosta should be ready to dock one ship by 27 Sept, the International Pier has already been docking one ship for a while.
They both hope to be able to dock 2 ships again by October - this is all according to local press reports, so nothing is certain but this is the latest I've heard.
Punta Langosta was due to open in Summer 07, although I've heard rumuors it might be later now.
Actually looking at the piers, you can see work is being done. They are pre-fabricating 'slabs', transporting them here and then dropping them in place.
In the meantime, ships continue to tender smoothly and they are also talking about putting two extra mooring lines by Punta Langosta in the high season to make it quicker/easier for passengers to disembark.
Hope that helps - keep an eye on www.thisiscozumel.com
