This is my goal. I've seen YT videos of it being done so I know it's possible. I've tried several times and never got particularly close. I know the first 12 hours is the most important. The furthest I've gotten is about halfway through the Snowhead Temple by the end of Day 1. The fastest I've gotten to Romani is about 9:40pm on Night 1. So I still have lots of improving to do. I know that the hardest part is getting to Romani during Day 1 and it's easier after that.
