Hey there. I have been to Phuket twice. Last year, i stayed in the Patong Beach Hotel. It was nice, but nothing special.
This year, we stayed in the Patong Merlin, and it was fabulous. The staff are much more friendly, the grouds are far better with 3 swimming pools! and its all round a better hotel.
I was very impressed with the Patong Merlin.
I am only 18 and you may think i want different things out of a hotel but i do believe that it would be quiet or loud enough for you. There was a swimming pool that older people used, and more younger people used the other two. When i say young i mean 20/30's, few children about. But there is a creche for children, a massgae parlour, a gym etc. The nighttime entertainment is 10 times better in the Merlin.
Trust me, if you can, pick the Patong Merlin. It may not be as central, but it is only an extra 5 minutes walk to Bangla Road and is still on the beach road.
Hope this helps,
Paul
