World of Warcraft players, come in!

Try this http://www.wowwiki.com/Zones_by_level

If you're around level 30 right now, you can go to Desolace, Southern Barrens, or Hinterlands. I haven't done much Alliance questing so I don't know which zones are the most fun for Alliance.

Most fun Horde questing zones for each bracket imo:
10-20 Silverpine Forest
20-25 Hillsbrad Foothills
25-30 Stonetalon Mountains
30-35 Southern Barrens
35-40 Western Plaguelands
40-45 Thousand Needles
45-50 Badlands + Searing Gorge
50-55 Un'goro Crater
55-58 Blasted Lands
58+ Outland

Dunno if Alliance quests are as fun in those areas, but I'd give those a try if you don't have any idea where to go. Once you're in Outland it's shared questlines.

I don't know which quests are more fun compared to others I've done. Being new to a game, exploring and discovering makes everything fun!
I went to Hinterlands and finished all quests I saw except...

 Spoiler

Where are the other 6 quests? >.<
Maybe I didn't look every inch of hinterlands but I'm already tired of walking. If I move I'll feel like I have unfinished bussiness there and it'll be annoying .

Stranglethorn vale is good for you either now. There is an alliance camp at the northern most part hard to miss coming south from duskwood.

also you can check out http://www.ding85.com/alliance_leveling_guide/. Follow it as much as you want, its more of a quick leveling thing for people with level 85s already, but you can still just check it out to see what zones have a lot of quest for your level and then go explore it on your own.

I might use it later if I keep getting stuck... Kinda tired of not knowing where to go next >.<
Thank you both!

EDIT: I'm NOT blind...
I just finished exploring all Hinterlands and I can't find those 6 quests >.<
