I booked a room in London £40 for two nights, in May. I thought I had a great Bargain (and it wasn't a typo) because there were various other prices available and that price was also available in June so I booked it twice (May and June) and cancelled a pre-booking for another hotel I had booked in June at £50 per night.
I had an email this week to say that the (£40) price was wrong and that I had to pay £120 per night or have it cancelled. Now, (if) I chose to re-book the other cheap hotel, I can't because its fuly booked so now I'd be even more out of pocket.
