I don't know, there are nice places. It doesn't do to make comparisons and if the sea is calm, the beach comfortable and it's a nice day, you might enjoy it. I usually have and have been to beaches here and abroad, some marvellous, some not so but if the weather is fine it's ok, the sea is the same wherever you are. I didn't go abroad this year, just up to Yorkshire and some of the beaches there are lovely. Bit far for a a day though! Maybe you could have seaside day and picnic with one of your daughters and their children. These are just thoughts, up to you what you do.
It's only when I'm on holiday that I swim now but next weekend will be down at my sis in law's, taking my in laws, her parents, where there is an indoor pool. I'm quite looking forward, always relax down there (W Sussex).
