well, we have returned  and we had a blast.
The trip  up was pretty  good. we stopped  on the US  side (at  about  four thirty  am) and   spent the (  remainder  of   the )night  in a  clean  but somewhat  seedy  hotel. For  seventy a night   what do u  want?   The  owner  is  a guy  from India  and he  son  told us , that the place was only  open in the summer months,with the winter  being  totally dead.
We got a shuttle and  crossed the rainbow bridge  by  foot. sure as hell beats  waiting  in traffic in a car.The customs took  about five minutes.I  even learned  that  you  only need  your green card , and  a passport is  for flying.Damn  wanted a stamp  in the passport. The guy  told us that he doesn't  do that
Our  hotel , the Best and western was  reasonable priced (The misses got  us a deal )and well kept.whats  more important  , we were almost directly  in the center of everything. we  could  walk  down a massive hill to the Falls  and those attractions  or ten or  fifteen  walk to Clifton  hill  and its  attractions.Everyone accepts  US  dollars , though   you    get  change in  Canadian  coins. 
 
There are four  major "things to do" when it comes to the Falls.
1) "Maid of the Mist" boat  ride.  
This is the highlight of the whole thing. Basically   you  ride a boat  (with a  provided  blue  poncho ) into the falls themselves. It was a relief too as we were there on a ninety  degree  day.Takes  about half and hour to forty minutes.Expect to be sopping  wet.if  you  go up top  its even  worse or better  , depending on  your view. 

 Bloody  great !
2) Niagra's fury . This is basically a   360  surround view , theater experience  , complete with fake snow , water and wind.yet another  poncho provided.
3) Journey  behind the Falls . This is where  you get as humanly  close to the falls as possible.  you descend in a  lift  and precede  through a set of tunnels out to  a viewing platform  , that  is placed next to the falls.plenty of spray and wet water , makes this ye another yellow poncho experience.pretty awesome.
4)White water walks .  To be honest these  last three are sort of time related.meaning that  you had to  be be at the gate  , by a certian time.  we decide to forgo the last  one ,  since supper seemed  much  more preferable  at  that time.
Best   to   buy a two day  pass  and chose which  two days to do all the attractions.  Doesn't have to  be consecutive. costs about $36  or something.
We had a few  days so we didn't rush  but  you can really do the whole thing in one day.
 Clifton Hill is  for all intensive purposes  an   amusement park , confined into  buildings on each side of the street.. If you  buy  a pass (well worth it)  you get  quite a few  attractions for half price. the The Niagara SkyWheel  is  a must see , the view is simply divine. plenty of other  things  to keep  you busy as well. The mini golf was excellent. Funniest thing was  sharing an elevator with SpongeBob SquarePants as we entered  by  mistake. Got a pic  on the  Camera on my cell phone to prove it as well.
Toronto is beautiful,and I learned the local pronounce it ,  torono  or  something like that  with out the  T. 
Duty free  is always  well worth it  and the liquor  supplies  got a huge refill.   $12  for a bottle of  Smirnoff is a steal.plenty reasonable prices  for whiskeys too.
Funny thing  happened at the border , as we were  clearing customs .   Replying to the  Officer's question to the purpose of the trip, The wife  answered  that its was kind of like a second honeymoon or so  on.  To which  he asked  how was it?    I replied   'Great  , but  was sorry to inform  him  , that the Canadian  side of the falls was just so much better"  He smiled  "  That's true  , but  you go there to look and  come here  to spend, your  money" and he was  right. 
Things in Canada  are   expensive and the taxes are 13%  or more. yet despite  this , the place is beautiful and the people we met  couldn't have been nicer.
So add this  to  your   bucket list as a must  do!
