Well, we have an outdoor pool and in the five years since we moved in, I have swum approximately 15 times, cost per swim about £200!
However we didn't have a heater, which we do now as we have tenants in there at the moment, and when we move back from abroad, we will use it a lot more as it will be heated and the children will be old enough to use it.
We put a full secure locked hardwood fence around ours and we now pay a man to open and close it, and come every two weeks all summer to keep it clean and the algae at bay (bad experience where it went completely green and we had to drain it a couple of years ago, very hard work!).
So yabu, I can see a lot of good times ahead with our pool now it is heated, though we close it between Oct and May so only use it during the warmer months.
However I can see your point, they are work that you might not want, they cost a lot to maintain, we had to put in a new liner, and the electric bill goes up obv when the filter is on!
