I don't speak Spanish. Is that a problem?

No, it is not.

The girls in are often from small towns. While language is o a problem, the warmth of the typical Latin gal can more than make up for lack of oral communications. Most of the gals are used to English speakers and know how to make you comfortable without a common language although most speak or understand English.

Actually Santo Domingo the Capital has many vendors who are used to speaking in English.  So there is incentive for the girls to learn some English.
