I personally would think learning Dutch would be very hard - the only thing i can remember from vacation last year was "biesluk" (chives), and i'm sure i've got that wrong.
A totally irrelevant sidenote: I spent a month in the Netherlands with my then-boyfriend who was on a Fulbright there. All the Dutch I learned was from watching American soap operas in English with Dutch subtitles. I couldn't say anything, but I could read things like "I hate you!" and "It's not your baby!" really, really well!
Oh, and I learned my numbers from the sex chat line commercials that were on all the time. They said the phone numbers over and over while they showed the numbers. Very educational!
