What a lovely way to celebrate your husband's 70th birthday! What do you have planned for this special day so far?
Travelling around and staying in each place for about 2 days is a great idea. This way you have enough time to explore and see everything in the area. You can easily explore the cities on foot or by public transport and rent a car
for the countryside trips.
I have collected some ideas and suggestions for you in this personal scrapbook
with itineraries and things to see and do. :) Once you have an idea of the places you would like to visit, you can decide the best route between these locations.
Let me know if there's anything else you need. I'd love to help! :)
