We have stayed near LTC in different airbnbs for several years, but the noise from Rainbow two years ago was so annoying ( it would start fairly loud at 8 or 9 in the morning, and go till 11 or 12 most nights ) that we are going to a different place further down the beach this year. The Grand Case Beach Club gets great reviews and is pretty far from the noise. Another option, which gets great reviews for a quiet stay at the other end of the beach is Le Petite Hotel though it does not have a pool and directly in front of the hotel the water has some rocks, so you would have to walk down the beach a little bit to find better swimming , You can see that from the photos here https://www.lepetithotel.com/gallery . Likewise, the Blue Esmerald has a few rocky sections in front of the hotel, photos number 2 and 11 on this page show the rocky sections https://www.bleuemeraude.com/language/en/gallery-bleu-emeraude-sint-maarten/ but not as bad as Le Petite. We have not stayed at La Playa, but go to Orient for the day and Orient is usually pretty windy and much busier than the Grand Case beach. If stepping out of your hotel , taking a few steps and sittilng in a lounger by the ocean for a mostly quiet day, either end of Grand Case is hard to beat. If you want more action on the beach , Orient is better, though most places are set back much further from the beach so you don't get the awesome views that you do from places on Grand Case. Topless is not uncommon on Grand Case, though not the norm.
