So my final Hans update for my Windows game. All I have to say in my defense is having a cold makes you loopyheaded and therefore do stupid things.

I continued to collect every hour up until about 90 min before the end of the event. At that point, I still needed 1 sword and 3 hats and only had one character to collect before the end. But I did get it down to 124 gems needed to buy the remaining items. With the 22 gems I had, I only needed to buy the $4.99 gem pack to have enough to Welcome Hans. And then I went to bed. I was able to use Paypal in the Windows store, so I can console myself with the fact that I used the small Paypal balance I had leftover and so it doesn't feel like I spent real money.
I made a couple mistakes along the way, but I don't think it would have affected things that much. I should have looked a little closer at the task requirements. I only had Anna at level 6, at level 7 that would have opened up her shared task with Elsa for the Ears. Also, I didn't think there was time enough to level Sven up to be useful, so I sent a character out on a 24 hr upgrade, and it turned out he only needed to be level 2 to earn swords. I was able to get him there before the end of the event, but probably missed out on 3 possible collections. Then, when I was able to upgrade Sven, I was dumb, and did it before I collected from the people with completed Hans tasks. So of course, they popped out Sven items. Final error, was I didn't have all my characters ready to collect as soon as I finished Hans battles. I had all the people with 4 hour tasks ready, but people with 2 hours I thought I had time to have them collect snowflakes, or 1 hr happiness tasks. After all, I wouldn't be finishing until after lunch...and then because of my cold, I slept straight through the 4 hr wait. So in the end, I might have gotten the single sword I was missing, but the hat drop rate was tough. When I collected after the event ended, I still didn't get more hats.
I didn't get the Frozen float, but I already didn't have the Incredibles float in this game. I don't foresee me doing anything like this again. If there is an event in March, while we are on vacation, I will just miss out.
