We plan to only stay on site at the Barcelo Bavaro Palace so I'm not really worried about drinking water that is served, I'm sure it will be safe on resort and we know only to drink bottled water. I've noticed comments here about not using tap water to rinse toothbrushes and to be careful about getting water in your mouth while showering. Is the tap water in DR any more 'unsafe' than the water in Mexico?? I've been to Mexico and I've always used the tap to rinse my toothbrush and never really worried about a miniscule amount of water touching my lips or my kids in the shower and have never had any issues. Just wondering if there is more concern with DR water. Thanks for any advice.
