Hi,
Caravanes or motorhomes it's a house with wheels my friends truck house that you can use to go anywhere.
There is not a law about where you can kite but please,you have to have common sense and not do it in front of the Sol Cayo Coco because to leave or return can be dangerous for drunken people or Childs or any other person.
They can not let everyone go in front of the hotels because of that but you can ride anywhere you want in Cuba,we use to go to Cayo Romano all the time and never had a problem.
The only thing you will have to pay once the 25 cut fees is you go to Guillermo but in Cayo Coco we don't charge for this, the school cover this fee for everyone.
If you rent the motorhome you can move from one spot to another one and stay at the hotels that we offer the service to connect the electricity and use the pool and other facilities.
Also you can rent in Havana and drive to Cayo Coco and go to Havana beaches,Santa Lucia(Camaguey) any other Cayo.Just be free to ride.
In Cuba nobody will arrest a tourist for no reason,not for kiting in a place empty or not dangerous for others.There's to many beautiful places to go there that really in front of any hotel is not worth it.
If you need anything in Cuba , write to me and I will help you:
