I don't know why this caught my attention, but "Costa Rica."
I've been hearing quite a LOT about this area, and it does sound lovely...I've even been given brochures physically and virtually. It's interesting.
There recently was a person who came to me wondering about purchasing something there?? I don't know what it is exactly or how it works, but you could actually enjoy (affordably) a piece of land or I don't know...
Me personally? I love San Antonio, TX food festival. They close up shops and the streets are lined with just about every type of food item you can think of!
But if I could have Christmas anywhere, it would be either Ireland or San Antonio (at least this year...I love to travel, even planning can be a wonderful experience)!
I would advise, however, the thing the person mentioned about purchasing land in these places...just investigate.
Other than that, every country and religion for that matter has a captivating expression of coming together for the holidays
