I dislike new Babylon - I've been there twice only. I liked the old one sometimes.

For me the main overall differrence is that the old Babylon was a rabbit warren of small places where some sort of fantasy game could and often was played out. Especially the many changing rooms with small shower spaces, the several saunas and steam rooms, the quiet jacuzzi.
The roof terrace was also really nice though the courtyard bar in new babs I like too.

The reason I dislike new babs is the cruising spaces are all too big and impersonal. Both steam rooms are just free for alls there's an assumption anyone who ventures inside has given permission for anyone to grab them. This was true in the darkest part of the steam at old babs too and I therefore rarely went there. At old babs that left me enough other places. At new babs it doesn't.

Beind constructive, it wouldn't be so very difficult to restore some of the old charms. The showers with wooden slatted partitions could easily be thrown in a small outhouse near the pool for example. They could copy the roof gardens of other saunas and use potted shrubs and trees to create a warren of cruising space in the far corner of the garden.
It would also help if all areas were open. Really don't understand the business logic of keeping them closed. Staff are paid so little anyway and so many guys want work. I know for a fact (at old Babylon and I assume new too) that one extra admission daily would pay for an extra staff member so why not open everything from 5pm onwards.

There is one good thing about Babylon which I always viewed as the place for farangs and Thais who want to behave in the less reserved way that is common in farang culture. This is the place for that "push and grab" behaviour and the fact it exists means other places are left to be more thai. Somewhere for everyone then. I used to go to old babs when first arriving from Europe because I was aware that my way of behaving had changed and it would be more difficult to score at Obelisks. After a week or two back I managed to behave sufficiently "well" to get what I want elsewhere.
