Situated in the heart of pretty Niagara-on-the-Lake is an elegant Victorian era landmark, the Prince of Wales Hotel. lt was built in 1864 and has gone through several name changes. Originally called the Arcade Hotel, then Niagara House, it was given its current name when the Duke and Duchess of York (later King George V and Queen Mary) visited in 1901.
The hotel was significantly expanded in the 1970s, though in a manner very consistent with its original design. It was thoroughly restored and updated in the late 1990s. It's lobby shows nice architectural and historic details.
I've never stayed here but did eat at its fine dining room once and thoroughly enjoyed it. High Tea in the Drawing Room is said to be a treat for those who enjoy delicious scones, sandwiches and pastries with their cuppa.
It would be a good base from which to explore Niagara Falls, the Niagara River, Welland Canal and the Niagara Wine Country.
