We've been a few times since we bought our AP and WS has been operated each time.
Last time we went we got there a few minutes before opening. We were allowed through the turnstyles (they do their bag check after you enter). As you enter Ghost Town is to your left, Camp Snoopy to your far rightand there's one more entrance just to the right which is the way to get to SB, X, etc. We decided to go on SB first. We were at the front of the line. (no rope, just a CM standing there) Just before opening they play our National Anthem (nice touch) and you can see the flag over the Wild West Arena. As soon as the park opened we basically ran for SB (they don't tell you not too) We made the first ride on SB. After our ride there were only about 6-8 people in each line (fits 4 per row) so it wasn't too bad yet. This was on a Saturday about a month ago so not during the summer.
After SB we went and rode X. Like PP mentioned, X is located in the far back right corner. The ride does tend to go down more than any other ride at KB so be prepared that when you get there it may be down for awhile.
Jaguar is an excellent 1st adult coaster. It was the 1st one my DD rode that wasn't for kids. She graduated to X last year on her 6th grade trip-now she LOVES it! If the line isn't too long for the front row, and you are a thrill seeker, go for it! You literally feel like you are going to fly off!
One thing about the line for X. Each gate is for 2 rows of seats (2x2). Many people don't notice this when they get in line. So if you are in line for the front row you may get the 2nd row (in the first car) If you want the 1st row you can wait through one more cycle.
Montezoomas Revenge is a great ride as well. You go upside down forwards and then in reverse. When there's no line they will let you ride without exiting.
La Revolucion is another great thrill ride. On this one where you sit makes a difference. I haven't figured out the where to sit when you are loading to make it the most thrilling-ask the CM if they can tell you.
Also Supreme Scream is good-Not as good as Maliboomer was, but still a thrill.
The classics are worth doing as well-Log Ride, Calico Mine Train, The Train,and The Stagecoach.
If you want to get wet-ride Big Foot Rapids!
Oh and their bumper cars, Wheeler Dealer Bumper cars are pretty fun-you are actually allowed to bump! Another ride that you don't have to exit if there's no line.
