Swiss Alps honeymoon

Hi I was looking for some help I don’t even know where to start,

We are looking to go from Dallas,Texas to Switzerland(or similar in the alps) during Christmas of 2026 for our honeymoon. We would like to stay in an all inclusive but understand that is not common so maybe something similar.

We would like to stay for a week and our budget is 8,000 USD but could have some wiggle room if they extra cost is worth it.

We would like to enjoy exploring a local town and culture, a spa, and some type of hot spring or similar in the mountains. Any help greatly appreciated!! Any thing else I might need to add please let me know.

Thanks!
