Hotels With Awesome Indoor Pools and Waterslides (Almost As Good As An Indoor Waterpark)
You don’t have to go to a full-fledged waterpark to find wet and wild fun! We love these hotels with great waterslides and added family-favourite features.
Chelsea Hotel in Toronto
This hotel is beautiful and family-friendly. Their heated pool is perfect for both kids and adults to enjoy. Plus, their Corkscrew Waterslide loops outside the hotel! You have to be a guest at the hotel to swim. Pool and waterslide hours are limited right now, so check their website for open dates and times.
The hotel also has a teen lounge with old-school arcade games, flat-screen televisions, a foosball table and a pool table. Adults are invited to enjoy it too! Also check out the Kids Centre, complete with dress-up, educational and artistic activities to keep kids having fun.

Mississauga Meadowvale Hilton
We have stayed here with kids and without and it is an ideal hotel for anyone. Our last visit was a quick Family Day staycation and the kids still laugh about how fast their mom zoomed down this curly water slide. The pool’s open hours have been carrying recently so be sure to check it will be open when you plan to stay.
London’s Lamplighter Inn
Look at this indoor lighthouse! The Maplighter Inn is a very popular getaway for families and an equally-popular hotel for travelling sports teams. A visit is high on our must-do list. Read our review here.
