We flew BA from LHR to Miami Feb 02 and the plane, food, service, seat back TVs etc were all excellent, exactly the same as BA Feb 01 Gatwick to Orlando!!
We drove straight from Miami to Hard Rock Hotel last year, as DH is good at sleeping, he had rested on the plane and drove, we arrived at HRH about 2am (UK time) so not too bad, as long as you're not delayed. We had stayed at the airport the night before at Heathrow so hadn't got up too early. That was with 3 children, and they slept a bit soit was nice to be ready togo on the first morning of our holiday!!
We had also paid £550 for 5 seats inc taxes, so it was worth it (to Miami)!!
