Matt,<br><br>Feed them before they turn in, make sure they drink plenty of water, and encourage them to "get up and go" if the need to urinate strikes in the middle of the night (tip them that a dash out the tent is not bad, especially if one leaves the sleeping bag "closed" - not zipped - to retain body heat while they are out urinating).<br><br>Some might be more cozy with some sort of blanket inside the sleeping bag, but if the fit is snug...<br><br>Have them put dry sleeping garments on and tell them to wear a knit cap to bed and NOT to burrow in and breath inside the bag (it's merely a bad habit on a weekend, but why start...)<br><br>Some get cold and some don't. If they have fun, that's important. A cheerful attitude on your part can't hurt, and it is usually very encouraging for a newbie if someone experienced has a warm cup of beverage ready the next AM... and a campfire if that is appropriate for your trip.<br><br>There is no end to the suggestions I could make, but I reckon you've already got a handle on things. Have fun!<br><br>Tom
