Key West - For Kids or Not?

We got back from Key West last week with the family.  This was our third vacation with Michael - and they are definitely getting more managable.  We picked Key West because I thought it would be a great place where we could enjoy the outdoors with Michael: the beach, the pool, walks around town etc.  We stayed at the Key West Marriott Beachside Resort.  Definitely had a nice pool but was a little far out from all the action of Duval Street. 

First a few things about us. We are frequent travelers and use Trip Advisor extensively to select accommodations for personal travel. This was our third vacation with our 13 month old son. I selected Marriott Beachside because they offered one bedroom suites with a kitchen and they were well rated on Trip Advisor. The hotel was lovely, the staff attentive and the pool was very enjoyable. Overall, I found the accommodations to be fabulous. However, I have a couple comments that I didn't read in others reviews that I think are noteworthy:
1. This hotel is at the intersection of Rt 1 and N Roosevelt. This is a very busy intersection...and consequently, fairly loud from a street noise standpoint. If you are in Building 2, which is directly next to S. Roosevelt, it can get kind of loud, especially if you are in a room closer to the lobby. However, you don't hear the road noise from the room, only from the balcony. I was kind of surprised that this had not really been mentioned in any of the other reviews (that I read).
2. The rooms are beautiful and have marble floors. The marble floors look nice, but are kind of dangerous from a toddler standpoint - we had a couple faceplants and head knocks that resulted in some bumps and bruises. The minute you spill anything on the floors they become very trecherous and slippery. They are also impossible to keep clean. I found myself wearing socks because the floors were rather gritty. Housekeeping would clean them everyday, but it seemed as if as soon as they cleaned them, they were gritty again.

3. If you have ever been to Key West, then you understand that the most fun part is Duval Street. And well, Duval Street is not quite as much fun when you have your 13 month old son with you.  It was nice to go down there, shop around, but to get the most out of it, you really need to go to Hogsbreath, setup at a table for a few hours and have a few beers?  You know? 

4.  Beaches.  We did go to Smathers Beach and Bahia Honda Beach up on Big Pine Key.  I think Bahia Honda was the nicest, although the Keys are just not known for the beaches.  It would have been nice if we could have setup with an umbrella and chairs - you would think someone would be renting them.  No dice.  The water was beautiful and the weather was lovely.  Michael had a great time in the sand.
