If you can figure out how to stay 6-7 nights I would suggest changing it. Most people that plan short trips regret it in the end. Our first trip was 4 or 5 nights, now we always book for 7 nights. I have seen numerous other first timers say the same thing as we did after the short trip, “Wish we would have booked a longer trip”.
We started out just booking 7 nights. We now go for 14-18 days. It gives us a night to have quiet time....if we want. We haven't had quiet time yet
