My friend redeemed a trip to Kerala fully funded except the flights for 2 people
but nowadays tripoto seems to give only discounts on trips rather than fully free ones.
just keep waiting for the right trip to come buy and redeem your luck!
Haven't reedemed any credits yet. But as far as I know, the packages are not fully paid. International ones don't cover flights and visa, they cover stay, internal transfers and one or two meals per day mostly. Please read carefully the terms and conditions and incursion before redeeming any packages.
