best places to plan/look into for Christmas/new year?

ok, im not the type that goes on vacations alot because of working fulltime. this year i already know i will be 100% free during the festive periods and want to go somewhere. family is trying to plan stuff but even they are so flip floppy with the "idk if we even want to go anywhere" or the "lets go to europe" (the original plan). i know its april but i just want to have good ideas of where are great places to go for those times.

for more context: i am a 33 year old man, plan to go alone, i live in the U.S.A but where i end up going, doesnt HAVE to be in the U.S. , i dont want to drop like.. a fortune type thing.. want to have it reasonably priced and stuff. idk exactly about budget because i just never gone traveling or anything before so idk how much is low budget/medium budget for places during that time.

if there are opportunities to meet people and not be alone then..cool. but at the same time i dont plan/expect to go somewhere just to be at like a nightclub the entire time or something. if any questions get asked I'll definitely reply and stuff... its just i want to have much planned before i start looking at prices and all that. i dont wven know when is best time once i know where ill go to start looking for plane/hotel tickets and all that.. so thats y ill just ask early.
