Hi Bulmer4NC:
I used a local moving company for my move without incident, about $300. I also purchased a "moving insurance" plan for the 1 day 24 mile move at $70. It provided a $10,000 payoff if the tub was "dropped, damaged or otherwise rendered unusable."
I tried using a local spa dealer to move it, but because my dealer (Artesian) went out of business 2 years earlier, the only dealers around were other brands. The earliest availability was 45+ days, one even told me 90+ days. Pricing was comparable.
The moving company I used had next day availability, showed up with 3 guys and moved the spa bottom down, never standing it up. They did such a good job I even tipped the crew (which is usually NOT something I do in this type situation).
My experience, for what it's worth....
