Welcome aboard, Brandy! My daughter sounds an awful lot like yours! She and I adore a special mani-pedi outing, so when we sail with Disney, this has become a tradition!
You're correct that
Senses Spa and Salon is for ages 18 and up. However, there is also the area of the spa called
Chill Spa for teens which includes all kinds of special treatments just for them. Right, but what about your 11 year-old? As long as she is with you, she can choose from and enjoy the Me! Bath Ice Cream Manicure or Pedicure. My daughter and I do this each time we sail. It's something she really looks forward to. She loves that she gets to pick the "flavor" of ice cream scented treatment, and then gets to enjoy soft serve ice cream during or after the manicure or pedicure. When we've enjoyed this special time, the nail technician has offered her the option to have a little hidden (or not so hidden) Mickey on one of her nails. Of course she chooses to do that! She's on a Disney Cruise Line vacation, after all! These relaxing experiences are such a special part of our tradition when we sail now, I can't imagine not doing it.
You won't be able to pre-book this manicure or pedicure for your daughter since she's not a teen yet, and can't officially choose that online during check-in. However, just pop by the spa when you board the ship and set up a time. In fact, the best time to swing by is when they're offering spa tours and then holding the spa raffle on embarkation day. My family and I attend this fun event each time and though I haven't had my name drawn as a winner of a free treatment yet, I'll keep trying! A few people win each time, so I'll keep going back!
Have fun planning, and enjoy your cruise, Brandy!
