That apparently was enough, or else we just wore them down. They set up an appointment and we went in to their office for an interview (an interview?! sheesh!). The lady there was pretty cold and bureaucratic at first, eventually when we had apparently satisfied her that we weren't trying to move there and work illegally, she warmed up somewhat, stamped all he papers, smiled and told us to have a nice trip. We had no troubles after that.
That was in 2006.
In 2008 we were headed back to Schengen-land, for a trip that began in Portugal, went through Spain, Morocco, and ended up in France. Having learned my lesson about Schengen bureaucrats and visas, I gave them only the minimal, specifically-requested info, and I lied about our itinerary: I said we would be in each country for the exact same number of days but would be arriving in Lisbon, and gave them the info for our hotel in Lisbon, along with their other paperwork and fee (all done via mail). They asked no questions, and we had the visa back in a week. No troubles (even though we needed a 2-entry visa, because we went from Spain to Morocco and then to France). All good.
Our return flight had us with about a 12 hour layover in London. I figured we would go into the city, see a sight or two, grab some fish & chips, then head back to the airport. But the cost and hassles for getting a UK visa were just not worth it. The UK will not answer any questions about tourist visas - you have to call a service that charges a minimum of roughly $15 to pick up the phone (and they were not very helpful, either). The cost for a visa for my wife would have been over $100, and she would have had to submit fingerprints - all this for about 3 - 4 hours in London. To that we said "bloody hell, no". So we spent a relaxing 12 hours in Heathrow on the way back.
Moral of the story: we're working on getting my wife a nice blue passport to avoid such headaches in the future.
Hope this helps. Good luck, have a great trip!
