EddieJuan - Certainly you can take a leisurely stroll along the beach to the other hotels - which is a favorite past time for tourists. Keep in mind that you will probably not be able to access the hotel, as the security people are usually watching for the wristbands . . . . . for the wedding I am sure they will be making some arrangements for guests.
Just for fun, go onto Google Earth and type in Puerto Plata, Dominican Republic. You will be able to have a look at the layout of the city. You will be able to zero in and the first thing you should be seeing is the harbour area. Follow the coastline (east) to your right and you will eventually come to the resort areas - first, the Coral Marien and Iberostart (the swimming pools are pretty obvious - hit the little crosses to identify the hotels). They are followed by a long stretch of beach and then you get to the Playa Dorada portion of the beach which includes a number of hotels some which are on the beach and others "in land". The golf course which runs through the complex is also pretty easy to identify. The first hotel on the beach in the Playa Dorada complex is Holiday Village (old Jack Tar). The hotel at the peak is Paradise, and Gran Ventana is next. Victoria Resort is not on the beach, but is one of the "in land" hotels looking out onto the golf course.
