Ok tony, i will give a bit more detailed report,giving the good and the bad and then those that go to cozumel will have a fair idea of what to expect.
From the bus station in playa del carmen men with 3 wheeler bikes will take you and your luggage to the ferry for 20 pesos ($2). The ferry was a nice experience.
The accomodation tony arranged for us was 100 metres from the beach and central to all the bars and restaurants,I was quoted $40-$45 dollares a night plus tax, tony got it down to $38 a night no TA?,You can rent a villa for $1000 ( a good idea if there is 6-8 people)a week but most of those are a bit far from the action.accomodation was basic with 2 double beds ,shower wc,and wash basin, ceiling fan and aircon ,it was cleaned every day and the staff were very helpful.Food is good value for money,some places give large meals and we noticed on a few occasions some people were ordering a starter that was shared and same for dinner like is served at indian restauants,all the restaurants we went to give taco chips with their local spices (watch out some will blow your head off he he).Tony recomended a GREAT chinese restaurant. You can hire scooters (?) be careful you will find that a lot of them will find faults when you return them,will blame you for doing the damage and so lose your deposit,you can also hire cars or even hire a motorbike from tony.
Taxis if you are new there,they will try to rip you off,always ask the price before you get in the taxi,at the bottom of the main street there is a sign from the good taxi drivers (union)who say we charge only for the taxi,and they are more fair.We are not mean but we got caught a few times,why pay $16 dollars when it is only $8.
Entertainment is minimal some street singers go around the bars for tips,the council had laid on mexican culture in the square.So when tony is back up and running properly it will be the in place to go because he has the edge with entertainment.
Watch out for the timeshares around the port and main street,if they don,t catch you on t/share they will try to overcharge you on taxi trips around the island or glass bottom boats.
Every shop on the front will try to persuade you to go into their shops,some even offer free drinks. If you ever want to buy anything ,never buy on the first day,look around and you will find the fairer shops.
The cruise liners dock quite often (massive ships compared to the mediteranian,As far as enjoyment goes, we loved it,but it was HOT.
The best piece of advice i can give you is this, whatever you want ,ask tony first, he will guide you in the right direction, and save you money.
ps, try tony,s baby ribs they are great.
