As stated above, you will need to explain by what you mean when you say a "Suite." Are you looking for more of a honeymoon suite with a whirlpool tub, or a family suite which offeres more square footage and an extra bathroom. Both of these options can be found at Disney. However, Family suites offer the additional space with additional bathrooms are can be found at the All Star Music and Art of Animation resorts.
As to the question of EMH hours. To be able to take part in Extra Magic Hours you will need to stay at a WDW Resort. However, and someone feel free to correct me if I'm wrong on this, guests staying at hotels that are located both at Downtown Disney, such as the Hilton, and other hotels located off of the Disney property will not be able to experience EMH.
Your best best to figure out which hotels will allow you to experience EMH hours is to go to the WDW website:
http://disneyworld.disney.go.com/ , and click on "PLACES TO STAY." All of the listed resorts will enable a guest to experience EMH.
I hope this helps you with what you are looking for. Good luck.
