Yes.

Letting your hot tub sit empty in the summer isn’t a problem provided that you have it properly secured with a cover. Having your hot tub covered is essential - in fact, one of the easiest ways that an acrylic hot tub can be damaged is by being left empty in direct sunlight. Doing so can actually void your warranty, so keep your cover on!
