Seeing that you will be staying at top end hotels, maybe you should use their limosine service, which I am sure they would provide for airport transfers. If I am not mistaken, Ritz Carlton is right in the middle of the shopping area, so taxi or other modes of transportation won't be needed for immediate shopping trips
Make sure you bring a lot of light material clothes because the weather there is always humid and very warm, and also do not forget your sunglasses and sunscreen.
If you happen to go to the street markets to shop, or just for the experience, never EVER take their first offer. Always bargain for a price that you think is ridiculously low. However, do not attempt this at retail outlets.
The 3 hotels you have mentioned are of excellent ratings and I am sure you would have an absolutely wild time
Do send me an email if you have any other queries in regards to the country!
Have a great honeymoon!
