Are there any folks who have done it and found something they should have done prior or during the process?

Thickness of the pad depends on local building codes, as well as placement on property, can't be too close to propety line. In some places you may need to pull a permit. Building codes can be found on line for your city or county.
Concrete pads need to be 3 1/2 to 4 “ thick.
Start thinking about the cement, what is the water weight. plus 4 people. Call a business that installs hot tubs and ask. Good Luck!
Find out your area's electrical code before you start.
Total the weight of the Hot Tub + the weight of the Water in tub (8# gallon) + the Weight of the Four Biggest people to use the Tub at the same time= the total weight the concrete will have to support, add 20% to that total for a safety factor!!! Call local concrete company (maybe more than one) to get their recommendation as to the thickness needed and the strength of concrete needed!!!!
