Sounds like a great trip. Two girls in one night in Santiago is impressive! However, I'd strongly suggest seeing a lot more of the country before deciding whether to make the DR your go-to spot over Colombia.
After spending around six months in each country, I believe the only things that are better in the DR than Colombia are the natural titties and the beaches.
