Hi Lesley,
Many thanks for your best wishes; I'm certainly hoping that all goes well. The hotel changes are frustrating, particularly the one whereby our PDC add-on is now about 23 miles outside PDC itself! It just gives the impression that everything has been cobbled together a bit, which is a little disconcerting but time will tell.
Bob - I've made some enquires about getting to PDC from Puerto Morelos and apparently its 'an easy journey on a big comfortable ADO bus that runs every 15 minutes and costs 20 pesos'. So it's definitely do-able if anyone wants to go.
Cheers
Mike
