Decent Resorts/Hotels for conference in the nature?

I am looking for a hotel/resort that’s decent and in or not far from Dehradun for a company conference. I live towards upper Rajpur/Sahastradhara, so prefer something this direction or in Maldevta or even towards Mussoorie. I’ll prefer not to go towards the city. If you all know of any high end places that you can recommend, that would be 👍🏽
