We have never been to Oasis Sens but we've been to Temptation 5 times and to Desire RM once. We absolutely love both Temptation and Desire and cannot wait to go back to both. Yes, Desire is expensive, about 2 to 3 times the cost of Temptation or Oasis Sens per night. We went in August and we paid $373/night for 3 nights. We loved it so much we tried to extend our stay but resort management would not offer us that same rate. They offered us a rate of about twice that, so we declined. Is it worth the extra price? For us, yes and no. Yes it is worth every penny and you will feel pampered and spoiled and happy and stimulated. But for us, we cannot afford that price tag beyond 2 or 3 nights, if that. So if we go to Desire in the future, it would only be for 2 or 3 nights and the rest of the vacation week would be spent elsewhere.
