Hi, just got back from my cruise...There were SO MANY 18 and 17 year olds...there is NO WAY they will be bored! You probably won't even see them! Just remember, they have their own "charge card"! So watch out! ha...
My daughter charged over $100 to my sea pass.., HELP! lol
Have a good time and don't worry...they will be busy checking everyone out and doing excursions during the day with you. good luck
