I just got back from Thailand and can perhaps give a fresh idea for your son.

It would be nice to have suites have a Buffet Breakfast setup as well as a Buffet Dinner Setup included in the cost of the stay so that way if you are going out for a meeting you don't have to wait in those long buffet lines and then when you return on nights that you are too tired to go out to dinner a nice Thai Dinner Buffet awaits you back in your room.

Another idea would be to offer a Customized SmartTV with content that the guest would be inclined to watch from CNN International to Netflix along with streaming movies etc. A day before the guest arrive they would login to the Hotel Portal with their preferences and register their payment info and when they arrive the mini bar would be setup as would their Smart TV.

Also having a ensuite Washer/Dryer that the Hotel Staff can operate as opposed to sending it out it would be done on your schedule along with Dry Cleaning and Pressing. A Hotel Butler would coordinate with the staff to do your laundry when you are away. You could register your away hours using the Smart TV and your needs would be met during your time away.

The Hotel also could provide a Thai Orchid Lounge for their Executive Club where Thai Airways operates the lounge with massage, food, beverage and a private Spa Suite with Turkish Hamams , Jacuzzi Suites and a Jet Lag Recovery Suite with the proper lighting, music and massage.

For late departures and early arrivals guest on the Executive Floor could use resting rooms and access the pool area as well. When the room is assigned a porter could take the luggage to the room.

One last idea is to have a VIP Tuk Tuk service stocked with Complimetnary Drinks and Snacks instead of a limo the Tuk TUk could have luxury seating, TV and Mini Bar.

I hope these ideas can help your son,
