I'm left wondering which version/dialect of Spanish would be acceptable/understood. The Mexican/Central American dialect has distinctions between it and the common usage in the US. Even more irony is that a visitor to Mexico from Spain might have issues because of the Castilian dialect used in Spain.
In my time in Europe while in the Army, I found some countries were more accepting of those attempting to use the native language. The least accepting I found was France where all I did was to irritate them when trying to use my combination of high school and guidebook French. The Germans were great and also wanted opportunities to try their English skills. The Italians were in the middle and became more accepting when they saw your money. I never tried Dutch during my one trip to Holland as they were very English-fluent. In Greece, you could get by in German as they dealt with German tourists all the time.
