Journey Through the mists

[Bruton the Iguanodon]

I've got a question. From the time Littlefoot sets off with Ali to get the night flowers to when they get back to the great valley, does a whole day pass between, or two days? Cause when they first get into the land of mists it looks like morning.

I also had this problem with 7, wondering if they spent the night sleeping in threehorn peak or just till the storm stopped.
