A swimming pool attched to a cottage is a delight on holiday. It is very nice to have your own private pool, just for the two of you. It is rare to find small holiday cottages possessing their own swimming pools; it is much more common for a holiday cottage to share use of swimming pool in a holiday park.
Either way, do take a look at self-catering cottages for 2 people with a swimming pool. There is quite a good number to choose from in the UK, we take it for granted that self-catering accommodation overseas has a pool available.
Lots of holiday cottages with pools for couples available all over the UK - find somewhere to go of interest and have a lovely break.
It can be a real treat to spend a little together time as a couple although when the children are young, this much depends on having supporting grandparents.
Alternatively, there are holiday cottages with pools where a babysitting service is provided and an occasional evening without the kids in tow is a possibility.
