If you have extra days, consider visiting the French Riviera, Swiss Alps or Greek Islands. If you have less time, consider cutting out a few stops and focusing on one or two countries instead. Don't forget to check for holidays and religious observances that may impact opening times of attractions and restaurants. And most importantly, wear comfortable shoes and embrace the adventure!
