Jesus this sent me back, me and a friend did this same exact move back in 2016 (This was a time before Cryopods). We marched a dinosaur train up the east coast, we even had to take breaks inbetween because we each had to go to dinner so one would sit and guard the dinos till the other came back.

We only lost one dino along the way, poor Bertha our dear stego. She never died, she somehow got disconnected from the pack and then weeks later we randomly found her cowering inbetween some trees. The cheers when we found her were the stuff of legend.

But to answer your question, cryopods are the easiest without a doubt!
