Second deco for F2P
I made a quick analysis in order to get the 2nd decoration in this event, and here is a summary of my results:
0) I will suppose you don't use your hurries in the 1st round, and that you use half of your golden hooks for the first round and the other half for the second.
1) If you complete the first round in 72 hours (exactly 3 days) or less, you can reach the 2nd round playing exactly the same way as before, needing only about 7 hurries in the 2nd round. However, finishing it in this timeframe is very rushed.
2) If 96 hours (exactly 4 days) or more have passed to complete the first round, it is very unlikely that you will be able to achieve it, because it means you will need more than 45 hurries.
3) Therefore, in a more realistic scenario, you need to complete the first round in 80 hours. This means you will need about 20 hurries for the 2nd round (you can even use your gems for this). For this case, I made a guide: You need to reach the red point in the first 24 hours, reach the blue point in the first 48 hours, and get the first deco in 80 hours (for example, in Mexico, this means getting it at midnight between Friday and Saturday).
Good luck to everyone!
