It just sounds like a lot of fun, and I can't be the only one who wants to try it.

So is it a good idea? Or something likely to go badly wrong? Has anyone on here tried it?

How easy is it to clean should we get it messy too?

It depends if you own it or not. If you own one, go to town. If you are renting one, I can personally say that I would not appreciate my kids potentially playing on a bouncy castle you were just boning in, no matter how well you cleaned it and I am pretty sure other parents would say the same.

Otherwise it's just a matter of privacy.

Luckily they don't run much on Amazon. A 9x9 bouncy house runs about 250.00 with blower. It's vinyl construction so you should be able to get it messy and it should clean up pretty easily with a hose.

Yeah, planning to buy one.
As well as the bonking issue you can pretty much guarantee a well used commercial unit has had plenty of contact with puke/piss/snot/shit from it's intended users. Even though it's been cleaned/sterilised by the hire company I'll still need to wash it several times first so it 'feels' clean.

Hygiene reasons aside the rental units are also just too big to fit in a hotel room.

Always wanted to try it, I love the feel of PVC/latex etc and it's so much better when slippery.

Someone on here did a video series of a gunge filled bouncy castle.

I imagine it's easy to clean with a pressure washer.

Just make sure whatever you do, pick a hotel with thick walls or that will be the most interesting phone call from reception you get . The blowers/fans that come with these things sound like small aircraft about to take off in small spaces lol
