A few years ago I was on 'Lanzarote', one of the Spanish Canary Islands...,
There I went on a Boat - just like a Mini Cruise to visit one of the other Islands. Onboard where almost only Spanish people, and although the tourleader did also speak several other languages, some times I couldn't hear it or didn't pay enough attention at the right time, and a lot of what he told was in Spanish. Luckely I also understand a little Spanish, otherwise I might have missed that the departure time had changed.
'Than I would have been at risk
of missing te Boat!'
So you see sometimes it can be helpful to know a little Spanish.
If you need to 'Brush Up' on your Spanish, there is a video taped presentation on DVD that learns you 'All The Vacation Spanish You'll Ever Need', you can check it out at Amazon in the link here below:
