Some poster(s) here said if you don't have someone with you, "you're screwed". I'd say that's a little extreme. Definitely better if you have someone with you though.
There really is no right or wrong here.
As clear as I can be whether I know you or not, whether you are Dominican or foreigner, if you are staying in any type of medical facility here within RD, it is encouraged that you have a family member, close friend, trusted neighbor, or caring person with you for that period of time. It is for your benefit.
I can't say more than that.
