I'll say that if you've never played a Person's game before then try not to let the time management stress you out too much. It can be a lot to juggle at first.

Generally speaking, you want to finish the dungeons as soon as possible in as few days as possible (finishing the first dungeon in 1 day will be tough due to running out of MP).

And if you want to use a guide, then do it and don't let anyone give you a hard time about it. It's all about making the game enjoyable for yourself. Not playing how others believe you should play.
