While they may be adding some shrines here and there, the follow is a good guide to just how big these quest areas are and I can't even be certain that I found them all. ToEE pt2 final fight map would not show up, so I am certain I don't have that.
I really, REALLY hope that they put in tons of random red names with chest and improve the loot options so people will take full advantage to the size of these maps.
ToEE Quest 1 Entrance
ToEE Quest 1 Temple Lobby
ToEE Quest 1 Map 1
ToEE Quest 1 Map 2
ToEE Quest 1 Map 3
ToEE Quest 2 Map 1
ToEE Quest 2 Map 2 - Water (Likely the Largest of them)
ToEE Quest 2 Map 3 - Earth (Likely the fastest route to the end fight)
ToEE Quest 2 Map 4 - Wind **
ToEE Quest 2 Map 5 - Fire (a close 2nd Largest) **
ToEE Quest 2 Map 6 - End Fight

Taking my time and getting lost a few times in quest 1, it took me 4 hours to map everything there. Quest two, not sure I got it all and that was still 2 hours. Exploring was fun... losing 6 hours of testing/bug notes to this editor wasn't 
I went back to Quest 2 to do Earth for myself, it is relatively fast.
I am guessing there is an additional option room for having all four stones, I have yet to visit that if it does exist.
After this goes live, anyone that says there are no dungeon crawls in DDO needs to be taken to a wood shed
