I would say it depends on the size and ages of your group. The two shower areas in the OG building are really nice as are the laundry facilities. Also the kitchen area in the OG building is really nice too and if you plan on just having 2 people in the room or closing the Murphy bed for a place to sit during the day I would agree with the OG building. However if you have more than 2 and you plan on having the Murphy bed out all the time then the BPK building has the benefit of a separate couch. Also if you plan to eat outside of the room more often BPK is much more conveniently located to Gaspy's and the boat dock.
