Will I be ready to go to Spain?

I recently tore my ACL and I am having surgery on March 19th. I am scheduled to go on a 10 day trip to Spain on June 9th, but my parents are hesitant to pay for the trip because they are unsure if I will be able to handle the walking. I will have had the surgery almost 3 months prior to my trip. Is this substantial time for my knee to gain strength for the trip?
