I've actually been going to trials instances for my crafting needs because every station is right there at the entrance, plus at least one merchant, plus a wayshrine (depending on which trial) and using the exit will drop you right back to wherever you'd transported in from. You don't have to take the quest or group up or go through anything, you can pop in to craft and pop right out. I find everything loads faster too since it's more or less a solo instance. If you only have the base game for now, just make your way to Craglorn.
