kiawahspa

I am in the market for a spa. I have a vacation house on Kiawah Island, SC. I live in Chicago and get to use my vacation house about 3 or 4 weeks a year. I rent out the house about 12-16 weeks a year, the remainder of the year the house sits empty. I plan to purchase a spa (portable?) and have it permanently sit on the deck in the backyard (regarding the deck - it will be rebuilt by my contractor to meet the required specs to support the spa.) I have been looking for dealers in the area for the past year. I only have a few to choose from in the Charleston area. If I want to purchase a spa from a local dealer it seems my choices are limited to the following brands: Hot Springs, Tiger River, Hot Spot, Solana and San Juan pools. I think it make sense to buy locally so that it can be serviced locally. I have been surfing the internet and have called a few places, the Envoy by Hot Springs seems to be about the right size. As I do rent out my house periodically I anticipate that the spa will be heavily used. I am interested in quality and durability and am will to pay to get it. I have poked around on this forum and have found some of the posts to be very helpful. I have also seen some of the threads deteriorate into some pretty heated exchanges (I am hoping to avoid this.) Any constructive input, regarding brand, quality, and quality of service would be greatly appreciated. Thank you in advance for your help.
