I'm looking at two options:

Option 1) Sept 27 - Oct 4 from Québec to Boston

Option 2) Oct 4 - 11 from Boston to Québec

I'm based in US. Are there any special points or things to consider when deciding between these two?
The way I understand, Option 1 I'll get to see fall foliage "in reverse", starting with more vibrant foliage back to towards more green, and also while cruising towards warmer temperatures, with Option 2 it's cruising toward cooler weather but also getting to see a more drastic foliage color change during the cruise. 

I am looking at Canada & New England cruises and I see that many of them go to Quebec OR Corner Brook. (There are also that go to both, and go to neither)

Question - for a late September/early October cruise, for people who can walk short-distances, but not including strenuous or complicated terrains, which destination is going to offer a better overall experience, including excursions and "on your own" sight-seeing? Specifically I am looking to get an understanding that if we can only visit one destination (Quebec or Corner Brook), which will be a better overall pick?
