After writing out the first episode's encounters leading up to the keep and adding up XP for the group (using average numbers of monsters no extremes either way) you end up with approximately 1K XP total. That's not per PC but total for the group. To be honest that is a BRUTAL run (9 total encounters if the group takes the hard way/combat every time) and I would have expected far more (level 2 coming into the keep missions) but YMMV.
