As we checked in, the staff said "This noise is only today, until 5pm". It was there every day, different weddings.

Not that I am exposing someone, they wanted as much publicity they could get

Day 1 wedding:

The people, somehow all the weddings over 5 days were Indian, are not of a lower sort. Could well be they came on own private jets.

Then it starts. Testing of sound equipment, every day different wedding, different crew, same testing from 10am to 1pm.
(all clips have sound, believe me, 100 times worse on the ground)
Encroaching public space
Would someone who is not Koh Phangan "Full Moon Party" sort of a customer come to a 5* hotel to go through this all day and most of the nights?
I complained but the officer said the weddings are their regular business. Almost wondering why I am not comfortable with that.
It surely is, but never seen it spilling out into everyone's holiday.
And we returned to the same hotel expecting the same quality (which is kept) and serenity (which was ruined by the weddings).
Bye bye Sheraton Hua Hin.
Visiting the new Marriott Hua Hin web site, they had a picture of a wedding arch next to the pool. I have to check that before booking, don't want to be forced witness anyone's wedding and the noise associated with that.
Seems they (5* hotels) are all pushed into that biz.
