Is there any tax/charge for goods delivered to the hotel?

You would pay taxes as normal with the purchase of your food, goods, and other merchandise. There is no additional charge to have items delivered to the hotel except what you are charged for delivery by the retailer, merchandiser, or restaurant. Please check with the hotel to find out if they even allow delivery to your hotel room because that may be a matter of security.

Don't know. Was there for a conference.

Would not think so.
