Jamaica 45 and Aruba 51 are two of the closest non-preferred buildings. We prefer Jamaica 45 because of the bright yellow buildings of Jamaica.
It's the same route in that the buses always travle clockwise. But depending on what entrance the bus comes in on will determine the order. If it uses the side entrance, then Jamaica is first. If it uses the main entrance then Martinique is first.
Somewhere in the middle. If the bus comes in the side entrance it's 5th. If the bus comes in the main entrance it's 2nd. Here's the map so you can see what I'm talking about.

The side entrance is right by the letter E in the map legend. The main entrance is labeled as such. I hope you enjoy CBR as much as we do. It's our favorite moderate by far!
