However the Grammar Police have a bone to pick with your use of the adjective "Dominican" to refer to the nation, which is a noun. So, from now on, please use DR, DOMREP, or Dominican Republic, or Quisqueya!!

That said, what you propose is well documented on the board, so just do a bit of searching.
A lot will depend on where you go: East Coast-> Bavaro, Punta Cana, Cap Cana, La Romana or North Coast-> Puerto Plata, Sosua or Cabarete.
Generally speaking, the hotels can do all of the arranging.
The only negative I have seen around here was one that dealt with a much too long delay in receiving the "official" Wedding Certificate with all the bells and whistles--> that is the offical stamps and seals...
Good Luck.
