If you go only for a weekend 2x 16gb SanDisc class 10 should be OK in terms of amount of data and speed even if you are into bird & wildlife photography where you are likely to take a lot of shots (Jpg Large Fine, Raw). As poster Rocky already mentioned you don’t have to use both slots but I always use both where second card serves as a backup. I would go for at least one 32gb card though – the price difference is not that huge and it may come handy especially if you go for more days trip.
I also wouldn’t go out without a spare battery as I think you are likely to run out of battery power sooner than of a space on your memory cards.
