Hi, there are a number of ways you can get to US from the Hard Rock:
1. Follow the path to the top of the water slide, then jump the fence by the big revolving guitar. Watch out for the snakes. *
2. Go out of the exit by the Palm restaurant, turn left go down the steps, turn left again and walk through the car park. This is the quickest route. 5 minutes.
3. Go to the ground floor, take the exit to the "beach club" (pool) turn left at the pool and follow the signs for the themeparks. As someone else said, this is the more scenic route and will take approx. 10 mins.
4. Go to the ground floor. Take the exit for the Water taxi (through the wodstock lawn). When you get to the Water Taxi area, turn right and follow the path to US. Approx 15 mins.
5. Go out of the lobby exit, turn right, go down the steps (or take the elevator) and follow the signs to the parks. This is the longest route. 18+mins.
The exit by the Beach club bar, at the right of the pool area is usually closed as it is now used as an employees service entrance/exit. This used to be the fastest way to get to the parks.
*only joking!
