Have I missed anything.

[PiperIsTerrysChoclateOrange]

Flights and hotels booked.
Pre book seats
Medical insurance
Car insurance.
Atol protected.
Car parking fees paid.
VISA still do do.
Passports to do.

Piper make sure you use Slidge's link. It is the official US government link.
Google brings up loads of ESTA scamming bastards who stiff you way over the odds. Most ESTA's are approved when you apply. If you have a slightly more complex case eg my DH has multiple passports, then it can take 72 hours or so to get approval.

Make sure you pre book currency to get the best rate.

Happy planning!
