Any question answered...

Ok so it looks like im going to florida over summer on a package holiday that includes a car,
its by a fair bit cheaper than doing it all on my own back as ive got a good deal however being under 25 the car hire place requires a young driver surcharge of $25 a day which ends up at £250 for the holiday which is a fair bit considering the car is 'included' in the cost of the holiday...

so does anyone know of a way round it

No. This is really common and something you'll find in the UK as well.
