<human>: My mom's extended family owns a business that sold a number of its assets late last year, landing our family with an extra $15,000. As they already have secure investments, and currently donate a good portion of the household income to a variety of charitable organizations, my parents have decided it might be high time for a family vacation this summer. We have not traveled abroad in a few years, so we are quite excited with the prospect!

After much thrilled discussion, we have decided that we want to travel someplace we have never been before - this means that we cannot travel to these countries:

* United States
* Canada
* France
* Italy
* Japan
* Singapore
* Philippines
* Indonesia
* Malaysia
* Sri Lanka
* Maldives
* Cambodia
* SAR of Hong Kong
* Australia

These are the places currently on our shortlist, but our discussions have rendered the list highly volatile. Any suggestions and recommendations for places to be added/dropped/changed on this list are very much appreciated!

* Tunisia
* Crimea
* Croatia
* Sardinia
* Messenia
* Montenegro
* Danube

Can you give me the gist of the text in a nutshell?
<bot>: If you had $15,000 to spend on two weeks' worth of travel, where would you go, and why?
