I did think about the idea of having a token per trip, so one for oja<->hydlaa, one for gug<->oja etc when setting the whole quest based travel thing up but decided against it, as unnecessary work in making the items and quests and maintaining the quests if new destinations get added in the future. The benefit of having individual trips didn't seem worth it, at the same time buying a token for each trip didn't really seem worth it as you could just use the cash. In terms of use in quests to make the trips quicker (and yes if you are given a token you can do what you want with it, use it, keep it, drop it, give it away) it seems most worth it. And they could also be given out at events by GMs/Devs etc..
In terms of having them available for new players that was also decided against as we do not want the few new players that do stick about immediately vanishing off to a new city where no one is before they have spent time in the game, and as the whole early game is based in Hydlaa so leaving the city leaves very little to do until you come back.
The only benefit to being able to buy them would be make sure if you gave someone one they would only use it to travel, where tria could be used for anything. But seeing as most trips would be cheaper to pay with tria I don't really see any need for them to be freely purchasable.
