Hi there,
I have stayed in the Falls countless times and if its the Embassy Suites you've booked, you picked a great hotel! The rooms, as the names implies, are all suites and very spacious - it is a fairly new hotel so not much wear and tear and the location is fantastic - you can walk to the 'main drag', the casino and the actual falls in under 10 minutes. I remember there is a nice big room on one of the middle floors that we went to for a complimentary drink when we first arrived that would be ideal for your cocktail hour..I think it was called the President's Lounge?? Ask to speak to the concierge at the hotel instead of the front desk staff, maybe they will be more helpful! Good Luck!
