You seem to have exactly the right concept of Kamala and should enjoy your time here. What's not to like- its quiet, for you accommodation is cheap even for top end hotels and despite some comments you can buy alcohol for private consumption. Kamala is NOT Patong (even when Patong is open) and that's what people like about it. I saw a comment that the beach is <deleted>- what more does someone need than two km of sand? On top of that you have several smaller beaches. Yes there's been debris on the surfline the past week but that always happens with the storms.
There are, as you can read a number of Phuket haters here- why they bother to post ad nauseum baffles me. They hate the place but love commenting about it. Some things about Phuket do leave a lot to be desired but the pros outweigh the cons. Even within Phuket you have the Kamala haters- personally Rawai does nothing for ME, give me Kamala any time. If it was carp I wouldn't live here.
At present there are 6 western type restaurants open on the main road- AP is opening weekends for sports but closed the rest of the week. Until the next review on 16 Aug they are prohibited from selling alcohol and are closing at 9pm. AP would be the only one of them with a pool table, when open. A couple of bars are operating under the radar but its pretty sad to see people that desperate that they are using their cellphone lights to drink by, (I kid you not!) may as well stay at home and watch tv with a beer.
