If they want to wait and see then let them arrive at Cassomir. They can still complete the Dream quests at Cassomir but will have to essentially "gauntlet" them since there won't be any ship events to break up the dream segments.
It also depends how much you told them at the end of Book 2.
Book:
IF you told them that Lowls is after the Necronomicon already and where it is located then they technically could skip Cassomir and the Dreamlands.
They would lose out on the chance to get their memories back, the stat boost, and the crazy experiences though.
If you told them that Lowls was just going to Cassomir then it can be more incentive to dig into the dreamlands. They will get to the town and have no idea what they are after besides looking for Lowls.
