There is an interesting thread on the go just now about the fluctuation in prices of Thomson/First Choice holidays. I thought I'd re-post as it may get missed as the original post is about the difference between two hotels:-
Our holiday(for 2 people) is currently £208 less than we paid although it went down to £368 less than we paid at one point and it's still 4 months until we go.
You expect unsold holidays to get cheaper close to departure time but not so far in advance. £368 is rather insulting to people who have booked early and already given them some of their hard earned cash to earn interest on for the privelige!
