You came to Tasmania and expected it to be something other than constant, nonstop humid rain? Boy, we sure showed you!
But, seriously, there are some really nice looking places in Tasmania. Coles Bay is a family favourite, and Queenstown looks really nice (although is the most boring place on earth ever).
If you want something a little closer, next time go to Richmond, which is a really lovely old Englishy town with a great little duck park / bridge / centre cafe kinda thing, and most importantly, a sweet shop.
But, yeah, better luck next time. The weather here is usually always total garbage, even when it's not raining, so it can be a bit of a diceroll. Thankfully, there's a lot to see that isn't more than a 1.5 hour drive out of Hobart (considering it's like a 2.5-4 hour drive to Launceston anyway), so you shouldn't really ever find travel too hard, depending on if you boated over your car.
