Mecca is a good choice to be with like minded people. It's good to hear you are willing to try the food served.
I understand you like to explore first before you take your family abroad but that's what internet, travelagencies are for. They inform you about everything you need to know.

I hope you can achieve your dream and if not: if Allah expects you to be abroad he would have give you a fat bankaccount. It's not the place but how we behave that pleases him.

Blessings to you and your family
