That's exactly what I'm doing. I'm half way through, having just taken the first set of exams, and received, but not started studying, the notes for Module 2.
The timescales are reasonable - I did Module 1 in a little over 6 months, and I plan on taking the Module 2 exams in around March or April.
You will need to take 14 days of holiday for each module - 10 days of brush-up, and 4 days of exam. That's with Bristol - some other schools arrange things so that you only need to take 2 days for the exams. Personally, I think doing intensive exams for 2 days would be pretty tough, but if holiday's tight it might be the only sensible option.
You could also look at London Guildhall - their course only has 1 week of brush-up per module, and they split it so that the exams for each module are done in 2 days. So you only need 7 days off per module. Having just done the Bristol brush-up, though, I really struggle to see how it could be possible to do enough work in 1 week to get you through the exams. But their instructors obviously think it's possible!
Good luck!
