QR50 per session is to much! Anyway, have fun!
I love swimming, but I cant do with ease here.
In my country to enter to Olympic size swimming pool cost us only USD1 = QR4! here QR30...Well!
Fitness club also provide swimming pool when we subscribe for club membership. In Doha, if you constance swimmer, you have to pay 2thousand per month alone for swimming!
You may opt to rent a compound or apartment hotel where swimming pool is available.
Well! better sleep at home! eat, sleep and eat again! cost only QR20 and some more, can gain weight! hahaha..;P
