We have just returned from a 2 week stay at Coba and have been looking to book again for November. We have also stayed at Tulum and each time we have been have been allowed to use the facilities of all 3 hotels.
I have just spoken with Thomas Cook (we are based in the UK) and asked them to look at a price for Tulum (they don't do bookings for Akumal or Coba) and they told me that as of 1st November Tulum guests can only use the facilities of Coba and not Akumal.
This is the first I have heard of this and cannot see anything on their website about it. Has anyone else head this? I have emailed all 3 hotels to ask them what the situation is but they don't always reply straight away so thought id ask here while im waiting.
