Yes the C&N Hotel is where we usually stay in Patong, its quite old but has some very nicely refurbished rooms (they call the new rooms "studios" on most booking sites)
Make sure its the Hotel and not the Resort that you book, the Hotel is the one nestled half way between Paradise complex and Jungceylon Center.
As for PP and Heart of Darkness being the new X-Ray, I will report on that once we get back, it may be that we hate it this time around and never want to go back!
