S.T.
we had a pop-up for years. how we loved it. so many awesome family memories created therein. we had the soft-sided version with a cooler (no fridge), a little coleman gas stove, two bigger pull-out beds and two small ones that were in the middle.
my dh and i weren't plus (i am now) and the pull-out (supported from the outside) beds held us with no problem. ditto the boys and dog all jumping and crazy on 'em. and i'm betting they build them even better now.
it was easy enough to set up. my husband's a cinch at all that stuff so he did it with minimal fuss, but in a pinch i could have managed it.
we didn't take a generator so we didn't use any electrical stuff. i'm sure you can get them with plugs if you want. we just took ice bags to keep the cooler stuff cold, and used an outdoor coleman stove for cooking so only used the little cooktop in bad weather. and we always took a canopy so we weren't totally stuck inside if it rained.
no port-a-pot, and i don't recommend it. stinky, even the good ones. even with tiny boys we had 'em get up if they needed to pee in the night. and boys are easy that way<G>.
no fan or space heater. even on cold nights the camper would get cozy when all the windows were zipped shut and we were all in there, especially with snuggly long johns and our good sleeping bags and blankets.
we had a TON of board games that lived in there. we took lots of books with us, as well as plenty of coloring books, toys, cards, and (when they were older) hand-held video games. we never got bored.
keep a little broom and dustpan in it- you'll track lots of mud and leaves inside and it'll make you crazy if you can't do a little basic housekeeping. have each kid bring a backpack of their own stuff, but no more. in that small space it can get overwhelming to have every kid bring a ton of stuff.
obviously lots of easy snacks. and tons and tons of wet wipes!
you'll love it. i miss ours, even though the boys are gone and the ol' man and i just tent camp now.
