Considering the Michelangelo Hotel Sorrento in Sorrento?

Amalfi Coast Bus Travel by Jetgirly
Busses connect all of the Amalfi Coast, from Naples all the way to Salerno (with stops in Sorrento). Besides being unreasonably slow (busses take twice as long as boats) the bus ride made me feel really sick. It's very twisty and turny, with lots of up up up and down down down. Then around and around. You've got decent views of the coastline from the bus... but it's not worth it in my opinion. In some places the busses are traveling on single-land roads, which leads to long waits, and in other places traffic is backed up for miles because some crazy person parked in the middle of the road! Why put yourself through the pain and torture when you could travel by boat so much more easily?
If you must take the bus, I've linked to Campania timetables below.
If you're a masochist, sit on the right-side window seat when travelling in the direction of Naples -> Salerno. You'll have the scariest view and the highest probability of vomiting!
