We spent a week at the Grand Case Beach Club in January -- it was our first time in St. Martin and we chose this hotel based on both Tripadvisor and personal recommendations.
I reviewed the Sunset Cafe and the Creole Rock Water Sports, both co-located at this hotel, separately.
The setting is gorgeous -- very well maintained gardens, a great boardwalk around the restaurant -- the outside of the property is pretty. The pool, unfortunately, was dirty and we never saw anyone use it.
Our room was fine -- not plush, but certainly clean and servicable. It included a full kitchen. It was useful when we realized how expensive most of the nearby restaurants were. The Grand Case strip is called the gastronomic capital of the Caribbean -- and the food was mostly very good, but also very expensive (we saw similar restaurants with significantly lower prices in Marigot). So we found a local little grocery store and self-catered for sandwiches at lunch, and brought home dinner leftovers to reheat in the microwave.
The included breakfast is just a small basket of breads, coffee and OJ -- so if you want more than that you have to pay for it.
But the thing that started to get to us more and more were the attitudes of the staff. You have to go in to the front desk area to exchange towels, so most people go in there daily. Saying good morning seemed like a chore to them. We didn't get many smiles, and when I asked a question about a nearby activity the response was clear annoyance that they needed to call over and ask for me. We definitely didn't feel like we got good value for the price of staying here.
While we enjoyed our time in St. Martin, if we go back again we'll find a different place to stay where the people enjoy working around tourists more.
