It is way more expensive to ride on a airplane! A train is WAY cheaper I know because i worked for these resorces.
Fly or take the train.
You can't take a train directly from the Shetland Islands to London. You can't even fly directly between Shetland and London. You could travel by boat from Shetland to Aberdeen and then take a train or fly from there to London or you could fly from Shetland to Edinburgh and either fly or take a train from Edinburgh to London.
Its usually a busier day to fly because its a weekend but not necessarily more expensive...
It is a short train ride - about 20-30 minutes.
To be honest, it's probably better to fly, but if you want to take the train, you will need to take a train first from Barcelona to Venice in Italy. Then you will need to take the train from Venice to Vienna.
You could fly, drive or take a train.
No, not necessarily. Most of the time, you hear about more planes crashing than trains running off the tracks.
December in Melbourne is their summer so it will be a bit more expensive to fly out.
You can drive, fly or even take a boat! Theres also walking or a train!
You can't drive to Churchill. You fly or take the train.
A bus or train or boat.
It takes 6 hours by bullet train (plus another hour to get you from Narita airport into central Tokyo) pand will run you about $250 each way. You can also fly to Hiroshima and then take the train from there, which will significantly reduce the time but won't be cheaper since no discount airlines serve Hiroshima (only the very expensive ANA and JAL). One option might be to take a discount flight to Fukuoka on Skymark Airlines and then backtrack by train to Iwakuni.
