Spending miles in school holidays.....

Many moons ago we managed to book a 'free' UC flight using 100k miles but this was before the girls were at school and so was in February. We are now pretty much tied to the Easter and summer school holidays.
For our flight in August this year I booked M+M as I couldn't find anything else available.
In the next day or so our flights will be released for our Aug 2012 dates and I am wondering if things have improved at all when trying to spend miles for trips during the school hols? I doubt it but thought I would ask? I also have an AMEX PE upgrade to use but again doubt I will be able to? We are tied to dates being 5/6th Aug to the 31st Aug.....
Am I best to just stick to M+M fares, I can make a saving of around £600 IIRC for the four of us....... or is it worth me giving the FC a ring tomorrow to see if they have anything?
Thanks in advance.
