Here are the top 5 greatest travel trends that Robb Report featured.

Private-Island Resorts

For the past 20 years, private-island resorts have overwhelmed the market. In 1979, Richard Branson opened the Necker Island in the British Virgin Islands. It offers Balinese-style villas, swimming pools, tennis courts and more than a hundred staff. The resort costs $78,000 per night. Soneva Fushi is a Maldivian private-island resort which goes for $39,000 per night.

Infinity-Edge Pools

In the early years, pools are just old boring rectangular in shape with a small waterfall or a mini grotto. Today, hotels have been offering infinity-edge pool to experience more fun while swimming.

Craft Cocktails

Pre-made mixes, syrupy sweeteners and maraschino cherries are the selection of cocktails in the 1980s. In 2002, a cocktail craze was introduced by award winning Milk and Honey in London. Today, the trend has spiked and bartenders now distill their own brands of cocktail.

Full-Service Spas

Spas are essential amenities today. The first full-service hotel spa opened in North America in 1986. Four Seasons Resort and Club Dallas at Las Colinas is a 431-room golf resort which provides private facial and massage rooms, steam room, sauna, whirlpool and cold plunge pool for leisure. The facility became a hit and today, a luxury hotel is not indulgent without first-rate spa facility.

Hotel Residences

Four Seasons Hotels and Resorts in Toronto was one of the first to introduce living in a hotel. The hotel has eight levels for condominiums, bringing the Four Seasons Residential program in 1982 for the first time. The residence became a hit. Today, the concept remains, hotels have 24-hour room service, daily housekeeping, on-call concierges and rental income.
