I've organised my transport to Hua HIn -Ms Na, have used her before.
Looking forward to the luxury of Eastin Grand Sathorn( exec deluxe- love the photos of the bathroom! We are only there one night. But I will have to try out the rooftop infinity pool

Then we are going to the opposite with a fairly basic hotel( along the lines of what you get in Goa). Been there before. This one is actually supposedly more upmarket than many others.
