Millennium Hotels and Resorts has announced plans to renovate its properties located in Anchorage, Buffalo, Boulder and Scottsdale in the US.

The group plans to refurbish public spaces such as the lobby and building exteriors at the 125-room Millennium Resort and Villas Scottsdale, with renovations expected to complete by the autumn.

Millennium intends to renovate 100 guest rooms including eight suites in the Main Tower at Millennium Harvest House Boulder.

Upon completion, the suites will offer kitchenettes and accommodations will feature larger, remodelled bathrooms, new furnishings and soft goods.

Renovations are also planned for the hotel’s public areas and two restaurants, along with Coaches Corner Sports Bar and Thyme on the Creek.

The redesigned wireless infrastructure at the hotel will allow guests to experience faster internet service within the public areas, guest rooms, and meetings facilities, according to Millennium.

At Millennium Hotel Buffalo, the refurbishments will include complete upgrades to all 300 guest rooms.

The group plans to convert 66 rooms to club rooms with enhanced features, while renovations are also planned for public spaces, meeting rooms and restaurants, which are slated to be completed by end of 2014.

Phase II renovations were recently completed to the entire conference centre space at Millennium Alaskan Hotel Anchorage, including upgrades to soft goods as well as audio-visual equipment.

While public spaces including the lobby, Fancy Moose Bar, Flying Machine Restaurant as well as the Deck at Lake Hood which overlooks Lake Spenard were recently renovated, the conference centre has now been redesigned to present a rich Alaskan lodge feel.

"In addition to Boulder, Buffalo, Scottsdale and Anchorage, we look forward to announcing renovation plans for more hotels in the very near future."

Guest room renovations are currently being planned for the hotel, which are expected to take place by the end of 2014.

Millennium Hotels and Resorts North America regional general manager Colin Wang said that over the next 12 to 18 months the company aims to make a significant investment in upgrading all of its North American properties.

"In addition to Boulder, Buffalo, Scottsdale and Anchorage, we look forward to announcing renovation plans for more hotels in the very near future," Wang added.

Millennium said that its properties in Anchorage, Buffalo, Boulder and Scottsdale will each be receiving phased upgrades ranging from total room renovations to public areas as well as exteriors throughout 2014.

Millennium has previously invested $22m for the renovation of Millennium Hotel Minneapolis and injected $30m to launch a luxury West Tower at ONE UN New York in 2013.

Millennium & Copthorne Hotels, which operates a portfolio of over 100 hotels, has seven global brands – Grand Millennium, Millennium, Grand Copthorne, Copthorne, M Hotel, Studio M and Kingsgate – in Asia Pacific, Europe, the Middle East, and North America.
