Hi Jessica!
Welcome to planDisney! I'm excited that you are only days away from your Walt Disney World trip! I'm sure you have planned a magical stay for you and your fiancé.
I don't like being the bearer of bad news, but it is highly unlikely that
Disney's Typhoon Lagoon Water Park will reopen for your February stay. It's currently closed for refurbishment and likely will not be operating again until after the winter. Historically, only one water park is usually open during the winter months. Since you are less than 10 days away and no announcement has been made just yet, the odds are not in your favor.
On the bright side,
Disney's Blizzard Beach Water Park is open and right on par with Typhoon Lagoon. While the theming is different, there is an equal amount of attractions and experiences to try out. Between Summit Plummet, Runoff Rapids, and Toboggan Racers, you'll have plenty of thrills during your visit. They also just added some hints from the movie Frozen to the kid's area if you happen to be traveling with little ones. There are some great dining options, including the Polar Pub where you can grab an adult beverage to relax with. I have a feeling your finance will be highly impressed with this park as well!
Jessica, don't forget that the
Walt Disney World 50th Anniversary Celebration is still underway across all the parks and resorts. This celebration has been magical in every way possible and I'm happy you get to take part in it!
See ya real soon!
Greg
