84 day Schengen Area journey. Lisbon-Paris then onward. Ireland or Georgia.

Hello thanks to those who can give advice and or contribute to this. I land in Lisbon on June 2nd coming from the US. I am excited to make this journey and to explore the great spots within the Schengen Countries. As someone who served in the military I have always loved the cultures of other Countries. This is just somewhat of a rough draft but places I would love to explore Sicily and Italy being the biggest one. I am 44 so not to young and I am in no rush to do this from start to finish. I am just curious and would like advice. Open to ideas. I will most likely use flights as my means between areas but not against any other forms of transportation.

Portugal-Lisbon and Porto.

Spain-Madrid, Valencia and Barcelona.

Italy-Sicily, Naples, Rome, Pisa, Florence, Milan, Tirano (this is where I would like to take the train into the Mountains.

Switzerland-Lake Moritz, Zurich

Germany-Munich, Nuremberg

Czech Republic-Prague

Germany-Berlin

Neterlands-Amstredam

Belgium-Brussels

France-Paris

I would then either goto Dublin, Ireland or head off to Tbilisi, Georgia and wait for good weather to head to SE Asia. I have not looked into other options. But I just would like to travel around long term.

I love culture and meeting new people. I am in no rush to do this as I could very well just stay in Italy the whole time, haha. I will for sure be coming back to explore more as well so this isn't like a once in a lifetime have to do thing. Just want to narrow down what to do and see.

Thanks in advance for your help and ideas.

Side note: I am not against any other means of transportation and really no budget.
