if you are at hrh, you definitely don't want to take that internal bus.
i took it one night so i could see all the hotels light up at night.
i had time to kill so it wasn't an issue with me. it was hot that day and i wanted to do some exploring on the hotels.
i took the bus from hrh where i was staying and did the route. the bus takes you to the front of each hotel. it is beautiful at night.
i timed it from start to finish. it took me 37 minutes.
it stops at each hotel and lets people off, and lets people on.
some people are so slow or had the driver wait for a friend that wasn't with their group. that held us up big time but not an issue with me.
if you are in a hurry to get to the parks, take the boat or walk.
