I don't often stay in hotels but am doing some exam trialling later this month and need to book 4 nights accommodation. It's not straightforward, is it? When I was looking last night, I found what seemed to be a good deal, within the budget allowed per night, and reserved it until today - but when I logged back in, it had gone up by £40! Thinking I might get a better deal elsewhere, I looked on hotels.com and found the same deal at the original price, clicked through to book, only to find that had gone up too...went back to check the original reservation and found that in just over five minutes, that had now gone up by another £37! Why do hotel rates change so much from hour to hour (or as in this case, from minute to minute)? If I book at the current rates showing, I will go over the budget allowed and won't be reimbursed the excess, but if I wait, I suppose rates could go even higher - then again, they might go lower!!
