Try to find the Embassy Suites deal. Best value for money.
This is an example off their website:

http://www.embassysuitesniagara.com/pkg-1night.html

This Package Includes:

Luxury 2-Room Suite Accommodations
Complimentary Cooked-to-order Breakfast for your entire party
$30 voucher for Fallsview Dining at The Keg Steakhouse & Bar overlooking Niagara Falls, may be used as $20 at T.G.I. Friday`s
Manager's Reception with 2 Complimentary Alcoholic Beverages

oh yea if you go to the keg - try to book a reservation either hours or preferably days before, when you book!

Bonus: if you can find one that offers a winery tour.

This type of deal comes up few times during the winter/spring.

The breakfast buffet the following day is quite decent considering it's included!

other recommendation:

go to http://www.tripadvisor.ca/Restaurant...s_Ontario.html

Don't waste ANY space on eating salad and just stick to the meats.
