Since GF only has one bathroom and blt has 2 bathrooms in their one bedroom I would stay with blt hands down. Now the one thing we have been doing is staying at a different
dvc location for our first night of each vacation so we get a taste and a feel for something different... this way if we hate it we know not ti waste an entire week. If we like it we know it's safe to book for a week during another trip. So I would spend my first night at GF to get a taste and if you like it then book an entire week the next time.
