They also sell water on the ship but it is not cheap - if there is none at the shop I said in my other answer - then the "town" is about 10 to 15 mins walk away and there will be a shop there. I never went to the town but the impression I got from other passengers was that it was a place to go to and leave fairly quickly as the locals are a pest. Try the duty free etc general shop first by the building where you " check in " for the embarkation. The airport at La Romana is V EXPENSIVE and is a non starter and it is also one to be careful with what you have in your hand luggage on the way home as the hand luggage checking staff seem to like to remove items they desire irrespective of allowances.
There is a shop next to where the coaches drop you off at the port in La Romana which is also a duty free but I am nearly 100% certain that in one corner it sells bottles of water and crisps etc etc .
I know of no medical condition, apart from an intolerance to chlorine, that requires bottled water. Bottled water is normally spring water which has virtually the same chemical composition as potable tap water. I would be very interested to learn of this condition.
I dont mean to be rude and i dont intend to tell you of the medical condition that this person has, they require water. I thought this sight was to help people when travelling abroad and not to be rude.
I feel sure that if you inform your cabin steward of the person's requirements for a constant supply of bottled water he/she will make sure that an adequate supply is maintained - it's their job. If you are buying a very large quantity you may even get it at a reduced rate. If you don't ask, you don't get.
The tap water on the ship is chemically treated salt water as far as I know - can't see you getting a reduced rate for bottled water from the ship - suggest you try to source sufficient prior to boarding but if you cannot then the ship will have enough supplies - it depends on how much you need per day as to whether it is worth just letting the ship supply it. As I said before threre is the shop at the port to start with. I seem to think the ship charged £ 1.50 for a large bottle in the cabin ( one litre ) but others may remember the price better as I never had the need to buy it on board.
