As a three year leaf owner 90 is too much, With heat battery degradation, I can only get about 50-54 miles (average) on a nice summer day with light AC use on one charge (and that's to just above turtle). Luckily I can charge at work. It is worse in the winter (maybe 35-40) when it was in the teens.
When you look at the leaf range you have to consider both winter driving and degradation over time. Winter will cut out maybe 20% more from your range - and that's freezing in the car with barely any heater (although my 2011 is very inefficient compared to the heat pumps offered in the SV/SL line). With the Texas heat you will loose 30% of your battery in 3 years. So whatever range you get new, knock off 30% (its actually a little more because of resistance stuff, but its a good ballpark). And yes, the stacking of 30% battery lose and winter can be very brutal.
If you want an extended test drive, enterprise here in DFW rents Leafs. I know this because my car was in the body shop (was rear ended) and the enterprise down the street (in arlington) had leaf's to rent, but all were rented at the time. You can get an extended test drive there. I don't know if dealerships would allow an extended test drive. I knew Chevy dealerships in the metroplex were offering weekend test drives of the Volt, but that was awhile ago. Also, don't discount a Volt so easily. If you need 5 passenger, then yea, it won't work. But the trunk of the Volt is surprising large for its class, and the Volt is also super posh - you get all the greatest stuff. The price did come almost in line with the leaf plus many places were offering 0% interest. Despite costing 5-6k more than my leaf, my wife's monthly volt payments are way less because of the 0% interest.
If a Leaf or Volt just won't work, your best bet is a Ford C-max Energi or a Ford Fusion Energi. Both available in Texas, bigger than a Volt/Prius and cheaper than a Volt. As mentioned PiP is not available in Texas.
Both Energi's get ~20 miles on electricity (21 by the EPA rating) and get an average of 43 mpg, better than the volt but not as good as a Prius (although its better than a Prius V). So if you want a plug-in but with some space and cheaper than a Volt - this is the way to go.
Good luck with your choices! As you mentioned we do have lots of charging stations around, so if you don't mind walking to your work then its a great idea. We also have a BUNCH of QC stations around (well more than most places). While it will cost you and additional 20-30 minutes of your time on a daily commute, it is an option if you needed it (via a cold day, lots of wind, or errands to run). If you haven't seen the map in my sig, check it out - it has all the stations in the metroplex divided by type and by company.
