That is really a tough choice. I also agree about the issue of trying to get a room at the Inn vs. a studio at BWV so that you do have two beds vs. the sofa bed and queen bed. We have done studios with a family of four and it worked, but no doubt about it, messing with that sofa bed is not my number one choice. On the other hand you would miss out on the kitchenette at the Inn and that is nice to have.
If you are already renting a car regardless of where you stay or if you are driving in, that to me makes Bonnet Creek much more appealing. Otherwise, even on the Bonnet Creek Lovers thread, the general consensus seems to be you need a car. So if you have to rent and also pay for parking at the parks that cuts into your savings.
B. Creek looks very nice, having that extra space and what looks like better pools would be a winner.
On the other hand, if you enjoy EMH, Magical Express, the
DDP, all that will add up to possible regret if you go with BC.
Good luck with your choice, I'll be interested to see what you final decision is!
