Hi,
Don`t think they would go far wrong looking at some place like Egypt or any of the Canary Islands.

The Gambia?

Egypt(Red sea) is a good choice . There are a vast array of hotels and most of them have a selection of pools but many hotels just heat 1 of the smaller ones at this time of year and they are just a little too refreshing . You would have to choose carefully . I know the hilton at sharks bay heat their pools .

lyn

Tautrito Princess in Gran Canaria also heat their swimming pool..but I think although the Canary Islands are warn that time of year, Egypt may just be slightly hotter.

Egypt would be good.

Cape Verde Islands - just over 6hrs.flying time.

thanks for the replies, they are going to gran canaria.
