I cannot agree. I am a cadet after TR in Budapest and had very good quality hotel just next to the airport. I know many people undergoing TR in differrent ATOs that Wizz is sending to, and none of them were complaining about hotel. There was a case when some students recieved medium quality hotel during TR in Sofia, so they wrote complain to person responsible for accomodation and she booked 5 star hotel for them for the rest of the training. Durining line training in Warsaw there is high chance you will get accomodation in Marriott Hotel just next to the airport. Also they don't save money on flight tickets, and whatever your departure airport is, they are going to book you flight with any airline so that you can comfortably get to Budapest or any TR destination.
