tram or train in the morning would be the best bet. either catch a tram, or just walk up from Dock 5 to Southern Cross (Spencer St Station), and catch a Lilydale Train to Hawthorn. otherwise, the #70 tram (and a few others, which i'll hunt down the numbers for) will take you out to hawthorn.
from where you are, if you don't mind walking, it should take you around 40 mins to walk from Dock 5 to Hawthorn. (now that i've actually counted the time, it seems alot longer than first thought, but might be enjoyable at the end of the day)
both Bridge Rd or Swan Rd (they run parrallel to each other on the way to Hawthorn) have heaps of boutique stores and cafes, which if i've read other posts correctly, you'll have a ball in :cool: also Toorak Rd and Chapel St aren't far away either! i assume you won't be bringing the 'tivo, so maybe Chapel won't be much use to you, except to laugh at all the vl's.
what date's are you in melb for? spring racing carnival is on for plenty of betting and drinking.
