Nobody that is remotely sane bothers to travel in August school holidays (apart from me, because I have to) but prices seem to be marginally lower this year. Instead of £375 a head from BHX/EMA, they're more like £350 - if you can pick and choose your dates, of course.
I think that reflects lower fuel costs more than anything, rather than panic selling due to any perceived tourist risk.
What I didn't expect was availability at our preferred hotel which had pretty much gone by this time last year.
