Thanks, DoctorP and teensmom! I bet my DSs would love to go back to the cabin and order room service, whatever they wanted! LOL
I think we'll definitely need to take drinks and snacks with us on this excursion. DH is diabetic and needs to eat at certain intervals, not to mention the fact that we'll probably ALL be hungry much earlier than 3pm.
teensmom: By the time we cruise next summer, DSs will be 16 and 13, so I don't have any worries about them being able to sit on the bus and then walk around ruins, for periods of time.
