I don't think these side stories should be faced either as fillers or irrelevant story. A good story is made of action moments and some quiet ones too, this was sure made for the 300th chapter, but it's also a good breaking point so everyone can rest from all the battles that have been going on(even though they have been awesome).

Would a 2week break be better? These are not "filler chapters". If it wasn't for these kind of chapters people would complain how the manga lacks character development. I see no wrong in taking a break from the continuous battles and showing a little bit of FT's "life".
Couldn't agree more with Kanic. One of the reasons that makes Fairy Tail one of my favorite mangas is that the story is not only based on battles, there is some nice background to it.
Also, there was nice character interaction in last weeks chapter, as for this one i was happy to see how Gildarts was doing and how he is together with the rest of the guild in his own way. So for me this was a chapter to be appreciated.
