There are plenty of posts on the C&N. Have stayed there many time and can highly recommend it. August will still be low season, standard rooms 500-600 baht, VIP room (only 2 or 3 of these) 700-800. Attached are some pics of the VIP room. bigger sized room, nicer bathroom will full bath. Standard room is still nice standard, a little smaller, and has a shower which goes straight onto the floor of the bathroom. Make sure if you go standard room you ask for a newer room, or new wing, normally this is no problem.
No pool at hotel but as mentioned by other BM's there is a pool at the end of soi sabsabai about 3-4 min walk away. Is clean and has a restaurant attached. 70 for all day pass, use as many times as you like.
If you enjoy karon fair play to you, but most board members like being a little closer to the action. No matter how nice the hotel is, or if youve already prepaid sometimes it just not worth the hassle of paying the joiner fee. Even though they are letting the girls in for a fee, ive found the attitude of staff (reception, security guards etc) can be quite unfriendly sometimes especially towards the girl, overall it can leave a bad taste in your mouth. (no jokes pls

)
Then theres the principle of paying extra money to a hotel that provides no service or value for it in return..
Id rather use that extra money they want for a joiner fee to pay for a hotel room in patong like C&N. Your hotel back in karon is already paid for, so use it as a base during the day or an escape for a couple of days if you need a break or change of scene.
Good luck and have a great trip
