My primary frame of reference is GCBC, and there are a lot of people I've met there who don't stay, or no longer stay, on the Dutch side. So I wouldn't consider that unusual. We stay a few days at Mary's Boon, which is site specific--Simpson beach is great, but other than that are perfectly happy staying on the French side. We still visit the Dutch side, and have a good time there, but GCBC and Grand Case are home for us.
