The Landing Resort and Spa is kicking its renovations into high gear this month as it pushes for a Dec. 12 opening.

Once the Royal Valhalla on the Lake, The Landing Resort and Spa has updated the majority of its 40-year-old digs in order to become a five-star hotel.

“It has a very storied past,” General Manager Jim Promo said of the transformation. “People used to say ‘Oh I’ve stayed there’ because it has this prime waterfront location.”

The resort, designed by new owners Jim and Nancy Demetriades, will feature an 88-room hotel, heated toilet seats, 55-inch televisions, custom linens, marble bathrooms and heated bathroom floors.

Nancy Demetriades said she was going for a certain “feeling” when designing the new resort.

“In designing The Landing, I wanted the building to have the feeling that it had been there for years,” she stated in a press release, “and I tried to achieve that with the stone on the outside of the building, the gas lights, and some traditional pieces in the rooms.”

The rooms — including a three-bedroom suite — are nearing completion, as crews install headboards, curtains and other fixtures before the grand opening.

Every improvement made at The Landing was done with five-star luxury in mind, Promo said.

“Their goal is to make it the best,” he said of the Demetriades’ vision.

To create the experience the owners were looking for, construction crews had to renovate most of the 40-year-old Royal Valhalla from scratch.

“They decided to strip it down, basically to the steel and studs,” Promo said.

Construction began at the site last fall on Lakeshore Boulevard and the corner of Stateline Avenue. It’s wrapping up almost a year later, with the final touches being made on the lobby, restaurant, spa, conference center, entryway waterfall and pool.

It’s a lot of hard work, but it’s already paying off, Promo said. The Landing Resort and Spa has begun accepting reservations, which even now are stretching out to September.

“People have already booked that far off,” he said.

During construction, an emphasis has been made on catering to skiers and snowboarders, Promo said.

Every room includes a gas fireplace, and guests are treated to complimentary transportation to the Heavenly Gondola and free ski and snowboard storage. Additionally, boot dryers can warm 96 boots at a time.

“A lot of us are from the mountains and understand the mountain community,” he said. “We know what the expectations are.”

One expectation the resort is planning on is demand for a lakefront wedding location. To this end, The Landing Resort and Spa has constructed a large wedding area that overlooks the lake.

“We’re going after the wedding market in a big way,” he said.

Jim Demetriades said the result had potential because it was close to many of South Shore’s popular attractions.

“When we first saw the property, we realized the potential for a five-star resort due to its unique location,” he stated in a press release.
