Is there any buses direct to Thorpe Park from London?

I'm sure i've seen an advert for one on the inside of another bus, but when
I used "journey planner" on the tfl website the fastest route had 4
interchanges and a 20 minute walk from the final bus stop at Norlands Road.

Last time i went to the park using public transport, I took the train to
Staines then got on the shuttle bus to the park entrance. The bus was jam
packed and the fare was well over the normal bus fare, so i want to get
there a different more civilised way. The thorpe park website is useless.

Thanks
