Kingdom 6

We have the predecessor to REI's Wonderland which is the very similar "Kingdom 6" and it was fantastic for family camping and easy to make into a glamping palace. The "garage" made an extra porch to sit and eat pancakes in during rain and keep gear sheltered. Rooms have a zip able divider. If you can find one in good shape used it'd probably be inexpensive yet glorious.

Winning and amazing for us was: Exped Megamats with sheets and quilts. An EE Accomplice for my wife and I on a Duo; each kid with their own single. We brought blankets like Rumpls as well for extra warmth. Tend wise our old REI Kingdom 6 has been amazing, especially with the "garage" add on. So big, zip up door two make two rooms. The garage gave us a place to cook and eat pancakes in pouring rain. Might get one used! Btw also huge wins: Dew drop led lights inside and out the tent. Solar recharging for the win. Plus solar Luci color changing camp lanterns. Polypropylene Persian carpets as doormats. Kelty camp couches. Eno Nest double hammocks with upgraded straps. So many good times...

My family of 5 has been camping about 3x per year in an REI Kingdom 6 for 15 years. It’s discontinued now, but it’s been awesome for us, even in thunderstorms in Yellowstone and high winds in Mojave, and we have never wished for more space. Enjoy your camping journey.

It's the tent I own. It's a solid tent, I'd gladly pay that for a second backup or for friends.

I have the REI Kingdom 6 and it fits my Megamat Duo with room for bags and a dog bed. They stopped making the Kingdom tents, but the Wonderland series is similar.

That's not a bad price. I think I paid $250 for a smoker owned Kingdom 6 with Garage and Vestibule that other than the smell was perfect. A couple washes with enzyme soap and I'm back in business. I don't think it will be as roomy as you would like though. We're 2 adults, 4yo and a small dog and it would be sufficient sleeping space but no extra room.
