Gotemba Premier Outlet to Haneda Airport

Hi folks! I've noticed that there is a Odakyu Hakone Highway bus service from Gotemba Premier Outlets to Haneda station. Is this an advisable route to take? Also, where do i purchase tickets for the bus? Thanks in advance!

Hello. I am Japanese.
I will be happy if I can be of any help!
I think it's advisable!
It's the easiest way to Haneda airport from the Outlet.
You can buy the ticket at Gotemba-Eigyosho"御殿場営業所".
It's near Gotemba station.

Have fun!

No direct bus from Outlet and No bus ticket office in Outlet.

Go to Tomei[EXPway(High-way)] Gotemba inter[IC/inter change] mae[東名御殿場] BS
or JR Gotemba sta[御殿場駅] first by free shuttle bus.
