Transport Gatwick to Heathrow?

[MinnieAbs]

We are going somewhere else before orlando, we fly from Heathrow and land at Gatwick. We plan on driving to and leaving car at Gatwick and then go over heathrow ready for our flight. So when we return we can jump in the car. What is the best way to travel between Gatwick and Heathrow please.

There's a National Express airport bus that goes direct between the two but that's about it I think.

Some get a taxi as it can be cheaper plus they may avoid traffic.

I have done national Express which is easy but dependent on traffic.

You can do a train too but involves changing somewhere but not easy if you have lots of bags
