If an 8 night trip, I wouldn't mind 4 nights at BLT and 4 nights at BCV. You'd be able to walk to 3/4 parks during your trip. Could even do 3 nights BLT and 5 nights BCV. I am taking just my twin DDs (15) in August and we are doing 3 nights at SSR and 2 at BWV...one DD chose SSR and other chose BWV so I booked both. We will have our car and I will pack us so we can just live out of our suitcases (will do 1 bathroom bag, 1-2 kitchen bag(s) and we'll each have our own bag for clothes and personal effects).
