So this game is super immersive, then in the middle of a Goblin Castle, the ancient reliquary of Selune your decide to camp for the night.....taking you to a forest, immersion breaking ugh. So quick suggestion from a guy who played and dmed way to much DnD.

Use a magic item you find on the Mind Flayer ship and have it once per day create a Lymonds Tiny Hut. You can even call it something different on the pocket dimensions so your party can wait for you there. It would give it a cool feel, allow a few less safe rests and be a cool gadget to deploy.
