My addition to the definition:

A halcyonic adventure-one of curiosity, openness, a willingness to allow whatever comes ones way to just happen

Highway, well because it’s a road trip and halcyonbyway or halcyonroad didn’t sound nearly as cool as halcyonhighway

Take the journey with me, I doubt you’ll be disappointed
