Father and Son Europe Adventure

Hi. My name is Todd Kramer. I am a single father of a wonderfully bright, energetic and curious 11yr old Son. We live in Santa Cruz, CA and enjoy so many moments together. We would like to travel to Europe this summer and visit several countries such as England, France and Spain. I am finding that it is very expensive to travel to Europe but I am so determined to share this experience with my Son that I am willing to work hard and live the dream.  I think this will be a great bonding and cultural experience for the both of us so we would like to go for 2-3 weeks and are going to need some financial assistance. Help if you can - travel suggestions would also be greatly appreciated.

Thank you in advance.
