Can't say I was that impressed with Karon itself (nice beach but very little else) but the Pacific Club is great. Spacious well-appointed rooms, a fantastic restaurant and a really nice roof-top pool area with a view over Karon bay. The staff are very friendly and helpful and the wifi speed was certainly one of the best I've had in Thailand. The bathroom had a decent sized tub for LOS and the shower was big enough for 2, which is always a bonus.
There's a lot of building work going on in front of the hotel at the moment and so if you stay on the 1st or 2nd floors then you won't have much of a view. I was on the 3rd floor and still had a pretty good sea view and if you were on the 4th floor then the view would be totally unobstructed. The rooms are well soundproofed so the noise of the construction work wasn't an issue unless you were sitting on the balcony and I didn't notice it as a problem when lounging by the pool.
If you're looking for somewhere quiet to relax then you won't go far wrong with the Pacific Club. I can't comment as to how guest friendly they are as I was with my girlfriend and although she puts up with my butterflying I didn't see a single girl in the bars of Karon that tempted me. Often there was nobody at reception when I returned to the hotel though so I wouldn't have thought it would be a problem to bring back multiple guests.
Can't help with recommendation for bars or restaurants in Karon (other than the hotel restaurant) as I wasn't really taken by any of them, but it was my first visit and I'm sure there are plenty of more experienced BMs that can tell you of all the great places I missed. I didn't take any tuk-tuks within Karon as my girlfriend refused to let me pay the mafia prices (they wanted 150 THB to go from the centre of Karon to the hotel) but a tuk-tuk to Patong was 250.
I forgot to bring the cable to transfer pictures from my camera to my laptop but will upload a couple when I get home if thats any help.
