At what level would you expect characters to come out of the combined WG4-S4? I'm wondering if continuing with the giant series might be feasible.
I would say it depends on if they were minimum or higher level when starting them and also how much "off the beaten path" adventuring they do. These modules have a good share of wilderness encounters that are not closely tied to the dungeon.
A large factor involved is how close to the RAW do you determine XP? For example do you award XP only for treasure successfully returned to a base of operations or for treasure discovered or won?
