Hey i'm actually having the same problem with picking between polden and woodland. I've asked my friend who has lived in woodland and he said that it is probably the best accommodation for socializing. Personally, i've picked polden but i'm thinking about changing my decision because catering can decrease your chances of socializing in my opinion (since you're not spending much time in the common room/kitchen), but that's just my opinion. Also i've visited polden and it seems pretty far away from the other accommodations so i think that will also affect the social life. I've also heard that woodland's rooms are much better and bigger. So yeah haha. Don't know if i helped.
