See, in 3e there's a basic assumption that an encounter between four 5th-level PCs and one CR 5 monster should drain away about 25% of the party's resources, which primarily translates into spells (and primarily the cleric's spells, which determine everyone else's total hit points). What that actually means is that you get up the morning, then have three encounters in a row that don't reallly challenge you. It's the fourth one that tests your skill—that's where you figure out whether you've spent too much, or if you still have enough resources left to finish off that last encounter. Then you're done. So basically, three boring encounters before you get to one that's really life or death.
It kind of makes sense, mathematically. The problem is, it's not fun. So what lots of people actually do, in my experience, is get up in the morning and have a fun encounter: there are multiple monsters that are close to the PCs' level, so the total encounter level is higher than their level. There's interesting terrain and dynamic movement. Sometimes there are waves of monsters, one after another. Whew! It's a knock-down, drag-out fight that could really go either way. And it's fun!
So you get up at 8:00 AM, you have that fun encounter, and you rest "for the night" at 8:15 AM. Repeat as needed.
It was like I was preaching again. I was on a roll. Andy said the people in the front might have been a little scared of me.
