I have been reading all your advice, thank you, and have booked a 7 night stay at the meridien in Khao Lak at the end of February.
Just in case anyone else is interested in the Hong by starlight tour and is staying in Khao lak. We have booked this tour and a transfer from Khao Lak on the 25th February, to save us all money if anyone else wants to book this date, I have been told by the company they will absorb the cost of the transfer which would normally cost B1000 each way.
We booked online at johngray-seacanoe.com/thailand/hong-by-starl…
You can also email them and I found them very quick to reply to my questions.
Really looking forward to this tour after reading all your reviews.
