I have one question, is that possible/advisable just walk in to the pool?
Yes you may. However, be attired properly because you will definitely get wet walking straight into the pool.
Hehehe... ish.. naughty la SD ni!
Answering you question 4321, yes you can just pop up at the pool on the weekends if you like BUT be prepared for :
1. Pool is closed due to DBKL program.
2. Kembara has many students and other customers at the pool on that particular weekend (no tanks, weights & other equipments for rental).
3. Be prepared to get wet when u are not attired properly because you will definitely get wet walking straight into the pool. Hehehehe...
Therefore.. it is still safer to call first before you go especially if you have to travel all the way there.
Cheers!
