They both sound cool, the storm and blizzard thing probably while the trainers are off trying to get something done but alas the weather.  mother nature decided "Nope. nope, you are stuck."

The Festival/Tournament thing is interesting.  What about a Festival that is about celebrating A town's history, a particular Hero?   A hero who saved the town's people a long time ago.  And at the end of all the celebrations of everyone making merry and chatting and dancing and all that good stuff.  There is a tournament to crown the Town's Next Hero?
