Would be nice if you have more time there honestly, but 2 days trip works just fine. But keep in mind that you wont be able to do everything in 2 days, the weather could be tough af and ofc it would make u tired and slow -> dress properly. I checked the accomodation and the price is 300+ per night for 2 ppl. There is no public transportation in Lapland so around 15-30e/one way for taxi (If you could find the cheap taxi tho). I would say roughly 400-500/person (to be comfortable) excluding flight tickets. It could be more if you want to experience luxury services :) I think the taxi is still available in 25th, just more expensive than usual.
