I'd have to agree with Gertrude on this. I'd also strongly recommend to you the value of learning in your local area as you will then be familiar with local geography, airspace, R/T, diversion airfields etc. plus most importantly local weather conditions and how they change... this will enable you to build your experience from a safe starting point after getting your license.
You'll also have the support of your local flying club - I think this is very helpful when you first start planning your own trips after getting the license so you can get advice and double-check your own decision making re- wx etc (remember the actual flying is often not the hard part... its the decision making that often kills people!).
I am also aware of several chaps who have returned from the US with CAA license earned over there who find themselves afraid and out of their depth suddenly in UK airspace and weather (although to be fair I don't think this is universally true..)
Hope these thoughts are helpful. Worried that this might be discouraging as you are looking to achieve your goal with limited resources: but I think if you can't stay current when you get back to Scotland from Florida you might risk feeling that you've wasted the money you spent training there? Have you considered other low-cost options such as microlights perhaps? Bear in mind also that as you have already got 35 hours, even though its a while ago, you'll progress very quickly through a local PPL course anwyay.
Good luck!
