I find that when travelling with children, a large shady terrace appeals to me much more than a very exposed sunny area.
We have been looking at villas recently for next summer and it surprises me that, especially in France, many of the pools seem set quite some distance away from the house surrounded by... nothing.
There is no way I could sit there for more than 10 minutes on a very hot day watching the children play in the pool.
I would much prefer a proper shaded area to relax in.
