That last bit of advice is well reasoned, the further you identify your needs and wants - the better advice you will receive.
Light pollution I would imagine is a lesser problem for a large scope - because on narrowfield work its signal to noise ratio (gathering and magnification of light from stars versus light from dust in sky) will be better than a smaller scope.
So if its setup or time optimisation you require with any rig to make the most of your circumstance you need to see what can be done.
Unless you have a permanent observatory and/or a permanent pier for a GE mount - set up will always take time - even for visual. If you go into astro imaging - set up will take a whole lot more time!
About all you can do is get help carting and porting your gear for set-up!
To optimise your time viewing - plan your targets ahead of time - during the day say using Cartes Du Ciel so chose 4 targets from 8-9pm or 5 from 9pm - 10pm etc and work out what eye pieces will likely give you best results. As per DJVege's suggest Argo Navis seems wonderful - and will making finding DSOs a breeze!
Good luck!
