Living in Sha Tin, the cross harbour bus stops are somewhat of a gateway to HK island for me. I…read moredon't like taking the MTR all the way there because of the million interchanges, and this route is just much more comfortable (although more expensive too).
Once you get out of the Hung Hom Station, the bus stops are just a minute away. There are actually two sets of bus stops - one closer to the station for destinations including Causeway Bay and eastern HK like North Point and Shau Kei Wan, and the other set is a little further down - you'll want to head here if you're going to Happy Valley and the south side, to name a few.
The one thing I like about these bus stops is convenience. It's extremely close to the Hung Hom station - they're practically next to each other. There are buses to pretty much every corner of HK island here. The bad thing though is that in the summer, waiting for a bus can be a seriously sweltering ordeal, especially if you're waiting for a bus that doesn't come that often. And it doesn't help that everyone around you is working up a sweat just waiting too. There are more bus stops at the area closer to the station so naturally it's more crowded, and at peak hour it might get confusing where the lines for the bus you want to take even start.
Getting to Causeway Bay is really convenient here - lots of buses - 102, 106, 112, 116 and 108 all go there. 112 and 116 are more 'central' as they stop outside Sogo. 108 stops near Lee Theatre, and 102 and 106 stop near Windsor House so it may be a bit of a trek depending on where in CWB you intend to go.
