Hi, Brandie, and greetings from Alabama the Beautiful! You are great to carve out a little mommy time on your vacation, and there are several ideas that come to mind:
1. Check out various
WDW Tours offered...they vary greatly in price and in duration. You could enjoy a wonderful three-hour experience by yourself and not spend an incredible amount of money. I've taken the Keys to the Kingdom Tour and would highly recommend it for adults.
2. Take in a leisure lunch or afternoon tea at the Grand Floridian and do some boutique shopping at its shops. Then, take the monorail around to the Polynesian and Contemporary to enjoy a leisurely shopping trip through the monorail resorts. (They're my favorite resort shops!) If you change your mind about the spa experience,
Grand Floridian Resort & Spa has truly unique spa services including aromatherapy soaks and baths.
3. Another time-away trip I like to take is to Downtown Disney. I like to order a yummy sandwich from the Earl of Sandwich and sit down outside to people watch. Then, I casually go through the various shops that my family doesn't have time for when we're together.
4. Lastly, I would definitely recommend your idea of taking in World Showcase at EPCOT alone. You can eat a casual lunch and take in the various presentations at the countries' pavilions and shop at all the wonderful stores that most parents are nervous about their small children visiting! :)
Whatever you decide, I hope you have a wonderful day, a relaxing time to yourself and a magical vacation!
