My sister and her husband

[Bella]

For the next days, my sister and her husband have a plan to explore Niagara Falls bus tours from NYC, and they are very excited. I hope so; this is the best tour for them, and they also came back with memories.  But they have one problem: they decided to celebrate the anniversary here, but they never visited any of the best and famous places to enjoy this thing, so if you know about it, can you share it here?

Celebrate the anniversary at Niagara Falls. It's a really good idea. I went to Niagara Falls with my friends. I suggest she take a boat ride on the Maid of the Mist and Cave of the Winds to get close to the falls, explore Niagara Falls State Park via hiking, and enjoy a helicopter ride at Niagara Falls. By the way, how many days does she plan to stay here?
