your rught the Dover is shorter and you feel like you are sitting on the ground. the reason for being short if someone wants to install in a sunroom , porch and is esticted by getting thru the door.The Dover is physically smaller in size 2 people comfortably, 3 crowded or cozy. the Camden i a 4 bucket seat design , no semi lounger like the Dover.i would say comfortable 4 cozy 4,Your Dover is 110/220 and the Camden is 220 only. and a 5.5 k.w heater versus the Dover is a 1 k.w or 4 k.w heater. as for getting in and out of the spas, as you get older it is going to get a little tougher to get out, Getting in all you need to do is sit on the lip and swing your legs over...As for the seating when you are looking at the spas on the brochure the Camden upper left will be similiar to the lower right corner seat in the Dover. the angle of the seats the Dover in the right 2 seats you are facing each other, look at the Camden the upper left you are siiting in the corner legs go at 45 angle across the spa the upper right and loer left go straight across, the lower right also angles in ,,, possible plying footsies..
Both are very good spas. but you are right not as deep as the rest of there line, i like the deeper seats myself, like spas that are 36" or 40 " tall then your not sitting on the ground, you might have to look at other brands to get that in a smaller tub. hope this helps you out.....
