The way to do it which was most efficient was, unlock the chocobo in Vesper Bay(there is one even though there's no crystal), Attune to the crystal in Drybones and Horizon. Then from the Vesper starter, you use Teleport to the crystal in Drybones, you get the Teleport spell very early in the game but you might have missed it when it unlocked, it's different from Recall which brings you back to the base you're bound to but has like 20mins cd, Teleport has no cd but costs money to TP to any crystal you've attuned to, oh and attuning isn't binding to the crystal, it's like unlocking the waypoint basically. Then you do your shit there, and once done you TP to Horizon(which has a crystal) then you can use a Chocobo Porter(automated chocobos) to Vesper Bay. There's set routes for them and you can't always go anywhere but back to the main city, but in this case you absolutely can go to Vesper Bay, it's like 30g for a 1min ride. You do this, turn in, take next, then TP back to drybones etc.
The key is you need to unlock every crystal and every chocobo and not forget about them. Chocobos have an icon over their head when not unlocked so they're easy to remember, but crystals don't and you need to make sure you attune to all of them.
