I'm with Dingleberry (see post above), which makes sense, because I play in his campaign, and he plays in one that I run.
I think the "reasonable amount of rest and being able to focus attention on things other than being alert in the wilderness or dungeon" is a pretty good middle ground solution.
In an old Star Wars (WEG d6, dontcha know) game that Dingleberry ran, we would do something similar, but one time there was a significant amount of Game Time that passed during which our characters were off at military training. At the end of that training, we received a number of skill points to reflect much of that effort, and role-played a few "in-training" moments to help get a feel for where the story was at that time in the game. I know it's important to be consistent, but sometimes there might be a way to work in a role-playing situation to reflect some of what was done, without burying the ongoing story in too many details about which motes of dust settle off of the scrolls the wizard's been studying, and how many new nicks there are out of the warrior's blade.
And now that I've gone on too long, good night.
