Do NOT book through Book Yoga Retreats - they engage in MISLEADING and DECEPTIVE conduct which is completely against what a platform about yoga should be about.
As their website enables, I changed the currency to pound sterling. I chose a retreat in England, run by a person based in England. I went back and forth negotiating with the retreat organiser and each time, she quoted me in pound sterling and sent me links to payment via Tripaneer for an amount in pound sterling.
Despite all of this, the payment was charged in Euros, meaning I was charged a 50 pound conversion fee from my credit card company. Note that the retreat organiser has no control over this - it is all the responsibility of Tripaneer.
I immediately asked Tripaneer to refund the amount and send me a new payment link so I could pay using a different credit card where I wouldn't be charged a conversion fee, but they refused time and time again. They were unable to give any reasonable explanation for why I was charged in Euros, and were completely unacommodating and uncaring.
I'd recommend using their site only to find out about retreats, then if you're interested in one research how to get into touch with the reatreat organiser directly and book through them. That way the organiser doesn't have to pay the commission to this pathetic company.
