I'm paddling over 35 years
I've done whitewater, surf, polo, Canadian, off-shore etc but I've never paddled an inflatable and ordinarily I wouldn't go near them. Not because they are inflatable as such, but because the performance characteristics of an inflatable would be something akin to driving a building site dumper truck, instead of a car on your daily commute. So broadly speaking, I'm in the same boat (pardon the pun) as iwillhtfu.
That said, I was impressed by some of the high end inflatables in Decathlon in France (soon to open here I believe) and was very tempted to buy. The reason being that we have a campervan but with the kids, all our bikes and gear it's just not possible for me to carry my boats. (17.5ft sea kayaks.) Thus, I've often found myself by the waterside, in France, wishing I could get out for a bit of a paddle.
In the end, I didn't buy and niggling doubts about an inflatable were a part of that. However, it was more down to the fact that even though it deflates and can be packed away, the bag was still very big and heavy and I just didn't have room. I'd still love to try one out and I know of other campers (who's only experience of kayaking is an inflatable) who swear by theirs. I however, have had to resign myself to renting when I am away. BTW - When I say I'd like to try one out, I mean a 'high end' inflatable. I wouldn't get into a 'low end' one ever.
For a recreational paddle where no real distance is involved, wind and tide or current are not going to be an issue (like a canal) and a rigid road is not a possibility, then I think a good inflatable has it's place. Obviously, with lifejackets, good swimming capability and good safety procedures etc. If you have no paddling experience then you should get some with somebody who has.
If by camping you mean loading up the inflatable and heading off out to an island on a lake or something like that the I would say absolutely not! Don't even think about it. That is not what they are designed for. But if you mean heading off somewhere say like Lough Key camping in the site and a spot of paddling around the lake shore then sure. So long as you are certain you are not going to get blown into the middle of the lake
Best of luck with it.
