We stayed in similar units in Sea Colony many times ourselves and always loved the experience. Our vacations were guaranteed to be fun and effortless. The oceanfront buildings are of high quality, particularly well-maintained and very tasteful. The best words you could use to describe them might be 'quiet class'. They are very clean, clutter-free and continuously updated.
Everything we needed during our vacations could be found in Bethany or nearby Rehoboth. Just steps away are the beach, pools, tennis courts, gym, basketball courts, cafe, restaurants, drug store, and wine shop! It was so easy to accommodate everyone in our family. Activities ranged from rollerblading, surfing the waves, building sand castles, swimming in the pools and ocean, bicycling wide shouldered roads, playing tennis, walking or just sitting on the balcony reading a book or chatting with family and friends!
