YANBU in your current circumstances - after a few abandoned camping trips I was ready to give up on it altogether but when I looked into the cost of alternatives I decided to give it another try.
I think there are different types of camping and if you decide to continue it is worth considering how to solve the problems that stop it being enjoyable.
If you are only doing very basic camping it might be better to wait until you are certain of reasonably good weather before deciding to go. Obviously it can be harder to find somewhere but it may save on wasted weekends.
As a single mum I decided to invest in gear that made life easier. I reckon what I've spent this year alone would have paid for a package holiday somewhere hot but I'm hoping it's an investment that will allow for cheaper holidays for the next few years.
A few things that have helped me are an inflatable tent, roof box and electric hook up. I take an electric kettle, toaster and George foreman grill so I can do basic food inside the tent if the weather is really bad.
If I'm booking well in advance I pay a bit extra for sites that have indoor pools and kids club etc so if the weather us awful I can still keep the kids amused.
I have a big plastic box filled with travel board games, pens, colouring books etc. This only comes out for camping so the kids get shoved in their bedroom with the box and I drink tea and read.
A cheap rubber backed door mat takes up no space at all but can really help keep the inside of the tent dry when coming in with wet shoes etc.
Waterproof trousers and wellies for the kids so they can still run around if it's raining.
I also try to have a bit extra out aside for wet weather days out - if I don't have to spend this I can roll it on to Christmas or next year's holiday fund.
At its best camping can be the best holiday going but when it's bad it's miserable.
I did one of the cheap sun holiday deals for a long weekend a few weeks ago and it was fab to just turn up and have a lovely comfy caravan but I've booked to go to a similar site for a long weekend in a few weeks and the price difference was over £150 so I will be camping instead.
A week in Cornwall last year cost me 200. A caravan at the same site for the same week would have been £1000.
I remind myself of this on the nights I am huddled up in my tent reading a book by torch light, drinking wine and fantasising about a hotel with a balcony!
