A world tour will improve your enjoyment of the game
You'll see cool sights, and most importantly, you'll acquire the teleport crystals that will let you transport to the other cities (well, close to them).So, Revalus, Zapdragon, Avator, QD and possibly Eolas and Icarii (depending on how much the last two have played). We can do this reasonably safely at level 8, its easiest at level 10 (less aggro in some of the intermediate zones).
It takes about an hour, all told, there is a long boat ride in the middle. I MAY be on tonight, will certainly be on tomorrow. I can do it, BD can do it (he'll just kill anything that aggros) and I bet a tag team of Aldayne and Anny could do it.
