Hi Catherine! Welcome aboard! I just spent some time in the Vista Spa last week while I was on the Disney Magic for a cruise, and can't recommend any of the treatments enough! Even just time in the Rainforest Room with no specific treatment is relaxing and rejuvenating.
"Alone Time" is one of the spa treatment offerings in the Vista Spa's Villa rooms. You can read more about it under
Spa Villa Treatments on the Disney Cruise Line website. Click on "Villa For One" and you'll see it listed as the first treatment there. This treatment includes your choice of one of a few different treatments, which you'll see listed, and then alone time in the villa room. I love the villa rooms at the Vista Spa, as there is an inside treatment room with an outside private hot tub and secluded bed to rest on, both on a private verandah, overlooking the gorgeous ocean views as you sail. There are treatments for two as well, after which you and your special someone can enjoy time together on that private verandah.
Either way, it's a nice chance to relax, be pampered and enjoy some quiet time in a private area onboard.
Have fun planning your cruise, Catherine!
