Nigel ,ive been looking myself for a zillion years to find a pool that's:----
1/Heated (in winter))
2/Long enough to put a few strokes together before you have to turn round (or bang your head on the other side)
3/Not to overcrowded with tourists (in winter).
4/Does not have ladies of a certain age stood in the middle of the pool exchanging gossip not intending to swim but stopping other people getting a few strokes in.
I,m still looking ( oh,no offence to ladies of a certain age ,I,m that age myself)
