I mean sometimes I see websites like (gambling tours, golden casino tours online etc) - the main thing is you fly to the phisical casino for free in any city of the world. But you have to make a deposit. Depending on casino deposit's price is near $5 000. The option that you pay firstly just a half or even 3d part of amount and then another one. Plus you shoud stay there from 2 days etc.
So, who tried such websites and services: https://fly2play.net/, https://www.tripadvisor.com/Attractions-g186338-Activities-c53-London_England.html ?
