I will be spending 4-5 days in HKG/Shenzen in July on route to SE Asia. I want to see specific locations in both cities but the emphasis is on shopping. Is it best to stay in Shenzen and take day trips into HKG or vice versa?
Secondly, HKG friends tell me to avoid HKG in summer. I regularly visit my in laws in malaysia so I am used to heat/humidity. Is HKG much different from say Penang at that time of year?
