Retreat in India/ around..?

Hi

I’m taking a month’s sabbatical from work due to burnout and chronic muscle issues (desk job, neck and shoulders are done).

I wanted to know if anyone has had a good experience in India/ Thailand/ UK/ places we can get Visa in < a month.. in terms of retreats (primarily yoga retreats). I enquired about Atmantan but it’s very expensive.. looking for something effective but in budget..

Im thinking 1-2 weeks.. any reviews from folks who have taken the retreat would be super appreciated!
