No!
Obviously you never been to Bocha Chica. Yes they are annoying, and no it does not spoil my vacation. Usually when i say no, that is when they decide they want to hang out with me and stike up conversation and want my Johnny Walker Black. Remember its not that they want to sell you anything its just that they want to see what you have so they can steel it from you or send their buddies to do it.
Do you honestly think that those Cohiba cigars are really Cuban? Be for real.
I took my Brother in law to DR for the first time and he saw a silver chain that those "Annoying people" were selling and when he got home 2 weeks later that Silver chain was not really silver, it was some black crap.
Now what I was trying to say was that at Bahia Principe there is a lot more chance for relaxation if you like that kind of stuff.
Personnaly i like the roudy crowds for example, I love my Merengue Tipicos and i would kill for a fiesta tipica do you want any more roudy than that?
