This is an old thread, but in case anyone is searching through, I wanted to update it with info regarding issues with the view mentioned above. I just returned from a stay at the Hilton Niagara Falls. Indeed the new Hyatt Regency has risen across the street (not done, but I think the main structure is topped out) surrounded by what will be the new location of Casino Niagara. While the construction detracts a bit from the overall feel of the view out the window, it didn't block the view of the falls, nor will the completed hotel block it, at least for most rooms. We were in a room on 29th floor near the left-hand side (facing front) of hotel, and the new Hyatt across the street only blocks the view of Goat Island. The view of both falls is intact, and should be just as or nearly as good from all rooms that previously had view. I'm guessing the location and orientation of the Hyatt tower was carefully chosen and negotiated. Since the Hilton is pretty new as well, plans were probably already underway and taken into account.

By the way, the hotel is great. Extremely friendly staff all around. Make your reservation from the hotel's direct web site http://www.niagarafallshilton.com/ for the best deals by far. They do two-night packages with free breakfast and $75 coupon for one dinner (also free casino shuttle if you like) which can be combined back to back or combined with an extra single night like I did. Unlike some "package" deals, the price for thes in the room type I booked (the Jr. Suite with "premium falls view" floors 17-22) was actually less per night than a single, even with the freebies. The buffet breakfast normally runs $20 Canadian. The dinner prices are pretty out there (think $40 or so Canadian for main course) but the $75 voucher makes it worth it for the view, which is amazing. Note that the room was only promised at levels 17-22, but they put us on 29. The hotel seemed very empty at this time of year as you might expect mid-week. We saw others, but elevators were mostly ridden alone and the whole place seemed pretty quiet. The room is pretty nicely done with extra sitting area, etc, and furniture that looks better than typical "hotel room chic".

HHonors fans may be interested to know that rising just a short ways away on Fallsview down next to the Marriott and Minolta Tower is a new Embassy Suites which looks like it will be the tallest hotel up there. (The top looked almost as high as Skylon Tower as viewed from the latter.) Its view will not be encumbered at all by another hotel. Looks like it should open sometime next year, maybe spring-ish.
