Terrible company, would definitely not recommend.
This year we flew to Turkey on a ticket from TUI. The tour turned out to be the cheapest in comparison with other tour operators, so they took a chance to take it. First, TUI staff should be more critical in selecting hotels for clients' vacations. We got the Trua Hotel Beldibi 3 *, which in fact turned out to be a solid 1 *, and this is according to the reviews of most vacationers.
