costa rica resorts guanacaste

Mid to late August vacation to Guanacaste area of costa rica or somewhere in the Dominican Republic?
Me and my girlfriend, mid-20s, are looking to take a trip in mid to late August. We have narrowed it down to the Guanacaste area in CR, particularly the Paradisus Playa Conchal Resort, or somewhere in the Dominican Republic (any suggestion for the DR would help also). CR looks beautiful, but doesn’t sound like much nightlife, which is fine if we have great places to see that are fairly close and the hotel has things to do. The DR sounds like a better nightlife, but not as beautiful and diverse outdoors. Any recommendations or help is greatly appreciated. Thanks!
Generally, Costa Rica would make for a better vacation than DR, and there is plenty of nightlife. However, the weather is better (more sun, less rain) in DR during August, so if that is important to you, i would go to DR, if not i’d go to CR. Either way, you’ll have a great time.
