You need to go home!! I remember that feeling too even though it has been a while since we have had a great vacation. You can just sense when the trip is over; it takes more & more to stay energetic, the kids are becoming complacent and the places are no longer new and exciting. Then the best part, once you get home and have to play catch up, you will need a vacation from your vacation! Good luck getting the kids back into normal life! ;)
