I booked the 7 night stay over the water looking villa and now I’m thinking of canceling it.

How hard is it to get full refund? Do I nee to explain to them about the reasoning?

Can Travelzoo transfer the voucher to another person instead of cancelling it?

I’m thinking with flight from Canada, excursions, food, drinks, domestic flight, snorkeling, tip ~ around $7000 all in for 2 people.
