Travel from Ariant cost

Hi, I have a simple question.

I am playing a challenge where I have no contact with mesos.
This has raised some problems with travelling.
I have recently finished a quest to unlock Manji's free travel to Ariant, if I travel there will I be trapped or is there a free journey back?

Thanks for your help.

 

Thanks I hadn't checked the ships, just assumed you would need to pay for a ticket.
The ship from Maple Island to Vic cost mesos until completing the questline.
NLC, World Tour, Singapore I think are locked.
If ships to Ludi are free then I think I can get to Florina Beach by finishing VIP ticket quest in Omega Sector...

 

Trying to be strict but I have occasionally picked up a meso and had to drop it again, felt dirty...
No currency including NX so TP rocks are out. No gach.
I thought I'd be locked in Vic island until this thread

It's interesting some of the things that I can't do.
Couldn't get the relaxer chair because the quest reward includes mesos lol doesn't help when I can't buy potions either :/
