In every major starport, you'll find a Star Tours Adventure Service droid. This droid, distinguishable from the ticket-taker droid by its gold plating, will let you travel -instantly- and at the height of luxury, for a modest 20,000 credit fee.
With connections to all other starports and shuttleports, as well as dungeons, bunkers, and points of interest throughout the galaxy, you'll find you're never far away from where you want to be. As an added bonus, you can take your very own Star Tours droid to go - using a High Tech Field Base camp, which is crafted by Rangers. Anyone can use these camps, and as the wealthy elite will tell you, you should never be without a crate in your inventory!
Do note: you cannot use the Star Tours Adventure Service while in combat.
