We had booked a 1 night break for 2 for Wednesday 19th July. I then booked Thursday and Friday night at another hotel also train tickets. When I checked the email confirmation to work out what tube we wanted I noticed it said check in on the 18th. I had not booked the 18th I booked the 19th, we had to pay again. Whilst at reception 2 other people had also had mess ups with their bookings. It was a very expensive night which ruined our whole trip.
