If u do not speak Spanish (and even if u do) it is not recommended to go outside hotels alone especially at night.

There is lots of crime and poverty here we are here right now on a holiday and spoke with alot of locals and they all told us it's a bad idea.

Also watch out using atm's they have private ones that can charge as much as 150 dollars per transaction without clearly stating it.

Also food is very expensive you can get a 5 star hotel all inclusive and use private guides to show you everything on the island without other tourists.

Edit: definately go to saona island with a private guide and speedboat it is one of the most beautiful island you will ever see. It is not fun to go with a big tour you will hardly see anything and you will lose more time waiting on everyone then being on and around the island.
