I was in a similar position last year, I needed to accumilate 60hrs before early June to start at a different EGBJ training provider.
My advice - if money is not an issue you would be mad not to do it in the UK - get experiece of british airspace, get to know the area and airspace where you will be taking your CPL it will give you a huge advantage for the course. Although the weather is crap there is rarely a day when you cannot do any flying at all and the experience of the conditions will make you a better pilot.
I managed 60hrs in 2 months comfortably. (April & May '04).
I also recommend a structured hours building programme if you can find one. If not, flying from a school that also does CPL training is a good idea - on those marginal days when I was undecided on flying, it was often a CPL instructor gave me a firm kick up the rear and said get on with it! (There is no better way of practicing diversions than doing it for real!).
BTW In my opinion Aeros is a very good choice of schools.
Good luck
