Hola! I went to Spain at the start of this year and, knowing no Spanish, I bought a phrease book and a dictionary to get me communicating.
However, I found that whole phrases are hard to remember and difficult to adjust to exact situations if you don't understand a word of them, and a dictionary is very time consuming to use. What I wanted was a short list of the absolute minimum vocab you need to get by, arranged so you can construct your own rudimentary sentences. Grammar, gender and spelling not required.
I couldn't find anything like that on the interwebs either so I've written my own, the absolute bare minimun guide to Spanish for travelling in Spain.
There. Now that's bound to have some obvious gaps - so have a think, and bung me your suggestions, however, remember nothing too specialist, and nothing that you can do easily with mime...
