Hi....we will be traveling to Punta Cana the week of Oct. 16. We don't have plan set in stone but we are thinking of staying at Ocean Blue Resort but we don't want to make a reservation in advance in case we change our mind once we get to that area. Is this a bad a idea? Are reservations at this hotel recommended? And price wise, will be more expensive to just show up? Any info is appreciated. Gracias.
