I made a booking with travel republic only to be told weeks later the price was being hiked up by over £1000 because a child would be 13 not 12 at the time of travel. Despite repeated requests they would not give any explanation as to what the increase was for or any breakdown. You cannot easily communicate with them, by phone its very costly. They don't just email you, you need to log into their online system to read and reply to messages, which would not work on my iphone while away. It's not live chat so can take them days to reply, 5 days the indicate- which to me is unacceptable when you are missing the chance to obtain a booking elsewhere. I ended up cancelling the whole booking and booking again with another company for the same hotel with the same age 13 children and for the original lower price. Still no idea what they were playing at!
