December/January Honeymoon

Got my wedding early December and we’re trying to find somewhere nice to go. If I had it my way, I’d either have an over the water cabin somewhere with nice weather, or go extreme and go to Scandinavia for a northern lights based honeymoon. I haven’t travelled much so I’m a bit useless with where to go. Ive looked at the Maldives and that’s pretty much bang on but it’s quite expensive. Just wondering if any cheaper alternatives etc.

Thanks!
