Congrats on planning your new tank. I definitely think your addicted if you want to spend your wedding money on an aquarium
My vote is for glass. Mainly because of scratch resistance. Coralline will grow on the walls and over time, just scraping that off will scratch the acrylic. That doesn't take into consideration occasional sand in the cleaning mag.
In my opinion, unless you have experience with acrylic, glass would be easier.
As Jim said before you can decide on glass thickness you need to know the dimensions. One of the main factors in glass size is how tall the tank will be, secondly how long.
Tagging along
