I have long disliked the huge dungeon crawl because they always seems to devolve into tedium. So this is an example of what I do in an adventure.
Not sure if this will make complete sense, but all the characters can make the skils checks, they get an amount of experience equal to their result. The best overall result determines what actually happens though.
38) Battle outside the Tower
The bleak stone facade of Kragspire looms several hundred feet up into the air. Myriad carvings, protrusions and balconies cantilever out over nothing creating inky pools of shadow upon the face of the tower.
DC Perception Result
< 15 You realize too late that the gargoyles are alive. You are surprised.
15+ The Gargoyles are alive. (800 xp)
Opponents: 4 combat enemies CR 10 each.
If failure, the gargoyles fly you up to one of the many balconies where you are left until such time as one of the gargoyles returns to devour you.
39) Tower Traps
Every inch of every surface of the tower is carved with runes. Writings in undercommon, terran, infernal, abyssal, and draconic assault you from all angles. Some of the runes draw your gaze towards them and some turn your head in revulsion.

So it is possible for the players to roll well enough to face no traps and no encounters. They get no treasure for doing so however but still earn some experience. By doing this I just have to create the rooms the monsters are in in case they have to face them. It is quick and by chaining them all together without out an opportunity to rest, it creates some good tension.
