I'm looking at a Horizon Club Premier room at the Shangri La and I'm wondering if there is a dress code for the Horizon Club?

I've noticed at some executive clubs they say shorts for men are not allowed. We'll be on holidays and hubby will be wearing shorts for breakfast or during the day (smart knee length cotton or linen shorts, say Hugo Boss, no denim).

Also, this room is in the Tower Wing I believe. What's the best wing?

Thanks.
