@DogInATent is the first person I've seen post negatively about bell tents but this is actually my experience also. We used to camp loads and I coveted a bell tent for so long, and since we got one a few years ago we haven't camped as much. We mostly just camp at festivals now and then don't take the Bell because it is far too heavy to carry and too big for a campervan pitch.
Issues for me have been that it is definitely cold. Especially the time I went just me and the kids. Everyone says get as big as you can afford, but I disagree. I think you'd fit in a 4m with no extra hanging out space and a 5m should be as big as you should go. It's harder to warm a big tall tent.
I can't lift the thing on my own. I can't even get it in the boot.
DH is paranoid about it getting mold or muddy. So set up time isn't any quicker because he spends so long being anal about the footprint we had to buy seperately and then cleaning it down thoroughly when taking it down. It's not the super quick up and down I dreamed of. But I guess that is partly a DH problem.
We often spend ages waiting for the sun to come out and it to dry before going home because we don't have a garden big enough to dry it. With a poly, you can hang it over a washing line.
Now my eldest is a teenager and often brings a friend it's a pain for getting dressed all in one room. I know we could buy a divider but the space isn't great with one. In fact the older all the kids get the more impractical it seems.
I actually didn't set out writing this post to put you off, and feel bad now. I don't regret our tent enough to sell it, I just think the bell tent groups are a bit unrealistically over the top about how amazing they are so bare that in mind. You can often get a bargain at the end of summer, we got a black Friday deal. Keep your eyes peeled. Don't spend too much.
If you have a big garden, you will find it more useful I think. I'd love to be able to set ours up at home for garden camping, outdoor movie nights, kids parties etc
