First tip: make sure you have plenty of free pods. You're going to drop stones by the bucketload, and some of them are very heavy. Having a Dragoturkey to offload the surplus into its inventory is a good idea too.
Second tip: you can make a bathroom stop in the little house at the dungeon entrance so you're all set afterwards.
