Hwin.
WYR meet Eustace as a dragon or the other dragon?
Eustace. Less likely to eat me. 🙂
WYR meet the fisherdess or one of the mermaids off the Narnian coast?
Mermaids, I guess.
WYR meet Glozelle or Sopespian (both book-verse)?
*wrinkles nose* Glozelle was the one that stabbed Miraz in the book, right? Then Sopespian, I guess. (If we were talking movie on the other hand, I'd go with Glozelle.)
WYR ride a flying creature by day or night?
Night! *daydreams about riding a gryphon at the dead of night while not going on a night raid that isn't going to work*
WYR ride a dragon or a gryphon?
(true that!)
Gryphon, I think.
WYR explore Cair Paravel treasure chamber alone or the Lone Islands with a friend?
Eeeesh...uh...the treasure room alone. Armor...weapons...shiny things!!! Tough decision, though.
WYR be bitten by a werewolf or a hag? 😛
Hag. I'd like to not have to deal with a dead werewolf's locked jaws, thank you very much. 🙂
WYR witness the LB Dwarves killing the Talking Horses or the Telmarine Conquest?
The Telmarine Conquest. I'm always so mad at the dwarves at that point in the book, because you'd expect better from them...
WYR see Peter's duel with the White Witch or Miraz?
Against Miraz is less scary.
WYR spar with Cor (swordfighting) or with Corin (hand-to-hand)?
Um Cor? That sounds weird but its true! 
WYR meet Peter or Caspian?
Peter.
WYR go to the Autumn feast (and not get eaten) or a feast in Tashbaan?
Honestly, I think the Calormene one would still be more pleasant.
WYR find yourself the victim of a prank from Edmund or Corin?
Edmund. He'd be easier to beat up if I was really mad at him about it.
WYR meet Griffle or the Lapsed Bear of Stormness pre-fight-with-Corin?
(lol, I would have gone with Ed but not for that reason!)
Griffle
WYR meet Poggin or Trumpkin?
