My wife and I vacationed for 2 weeks in Curacao last year. We rented a condo thru VRBO that was in Westpunt, right on the ocean. Diving was great! Just put on your gear on your back porch, walk 25 yards to the cliff edge, go down the steps to a platform, and make your entry. There was a ladder there to make an exit. 60' depth was about a 50 yard swim out. Great reefs, good visibility, and lots of marine life. There was another exit spot about 200 yards away, so we could plan our dives many different ways. There were many other great shore diving locations on the leeward side.
When we needed a break from diving, we could go to Willemstad and had a great variety of good restaurants and shopping. If we just wanted to get away from everyone, there were miles of trails at several locations on the windward side of the island. Just be careful of the cactus and thornbushes, they are SHARP.
Two weeks were great, but it would have been nice to stay another week.
