I don't know much about that adventure because my kids have been playing on and off for a while now and their characters have just reached 8th level. I decided to drop them into H3 - Pyramid of Shadows this weekend. I have to say I really recommend it.
This adventure has some really good RP elements for them to get into and some very interesting fights. It took them six months to get from level 5 to 7 but they did a whole level this weekend in the Pyramid.
After we packed away my 9 year old daughter decided it was time we talked about Paragon Paths!!
Needless to say I am one very happy Daddy right now.
