In one- or two-star hotels, you might be content to get free waffles or a complimentary newspaper in the morning.
But some luxury hotels go beyond typical perks, according to the travel review site Oyster.com, which recently released a list of the nine most extreme amenities offered at hotels worldwide.
For example, the Ritz Carlton in South Beach Miami employs a "tanning butler," who patrols the pool, applying sunscreen to guests.
At the Lanesborough Hotel in London, a tea sommelier is available to help guests during afternoon tea service.
The Hotel deLuxe in Portland, Ore., offers access to a pet psychic and a pet psychologist for animal guests that are having trouble with the pressures in their lives.
The six others are a gondola couples massage at Loews Coronado Bay Resort, San Diego; monogrammed bathrobes at the Hotel Ritz Madrid; room service for pets at The Lowell, New York City; famous artists in residence at the Andaz Fifth Avenue in New York; a fragrance butter at the Rosewood Hotel Georgia in Vancouver; and a soap concierge at the Viceroy Riviera Maya in Mexico.
Waiting is hard
Among the key findings in this year's J.D. Power airline satisfaction report were numbers showing that satisfaction levels among travelers drop sharply when they are required to wait for boarding passes and luggage.
The annual study that surveyed 11,370 travelers who flew in the previous 12 months found that satisfaction with an airline was 41 points lower if the flier had to wait 15 minutes or longer to get a boarding pass, compared with those who waited less than 15 minutes.
The study measured satisfaction on a 1,000-point scale.
The same survey found that satisfaction levels also dropped 41 points for passengers who had to wait more than 15 minutes to get their checked bag.
And if an airline loses or misplaces a checked bag, satisfaction levels drop even further, 51 points, compared with travelers who get all of their bags upon arrival, the study found.
