I am type-I diabetic and almost always use the

To answer your last question, the CRT meals will take 2 TS credits per person.
Like the pp mentioned, sugar-free or NSA desserts are available at most places, and where they aren't or they aren't to your liking, it is usually easy to get them to sub a fruit plate or something similar as your dessert option.
For snack credits that do not contain large amounts of sugar, I have gotten:
Whole fruit or fruit cups
Pretzel
Chili or soup
Carrot sticks with ranch
Yogurt
NSA ice cream
popcorn
pickle
chips
NSA frozen fruitsicles (like those dole frozen-fruit bars from the grocery store)
funnel cake without the powdered sugar
Of course, as you mentioned before, with all of the walking and activity sometimes I actually need a sugar snack - those are very easy to find. For TS meals where there is a dessert I just have to try, I order a salad or eat low-carb something for dinner.
As for sharing, we do it a lot - there are many 'large meal' CS options out there where it is more than enough food to share. For example, at Cosmic Ray's in MK they serve a meal that is half of a roasted chicken with mashed potatoes and green beans - with the large diet coke and dessert (the SF brownies are not bad, although we usually get a 'regular' dessert for my travelmate to enjoy as I am not a chocolate liking person) and that is 1 CS credit. Sunshine Seasons at Epcot and Flame Tree BBQ at Animal Kingdom offer similar shareable (read:
large) options for CS. We generally book our 'big' (TS) meals for late afternoon, kind of a late lunch/early dinner deal. We'll share a CS lunch a little before 'normal' lunchtime (10:30-11) and have the TS meal between 4 and 5, then if we're still going late at night we'll split another CS around 9-930. I do carry granola or cheese crackers in my bag, along with the glucose tabs, just in case - but rarely if ever actually eat them. There are just too many things to spend snack credits on
