We got so excited about all the fun we were having, that we started inviting friends on weekenders. Our trailer is tiny, so of course we can't sleep them all. They had their own site and tent, but we offered all the conveniences that our little trailer has; a bathroom (for #1 only), kitchen and dishes, a cool spot to sit for a spell in the A/C, etc.
Everytime, it has turned into an aweful lot of work for us. Seems trivial, but doesn't feel that way when you're doing it all. More dishes to wash, food to cook, coffee to brew, blue totes to empty, and on and on.
Not to mention, staying on your best "company" behavior 24/7 gets very old. Sometimes I just have to fart or yell at my kids too much or get frisky with my wife. It's downright tiring to host.
We do enjoy having them, and are glad we can help them enjoy the hobby. However, it does change what we get out of a trip. We sure don't come home relaxed.
