(3 p.m. EST) -- Luxury cruise line Windstar Cruises has increased its daily hotel service charge by $1.50 per person, per day -- bringing the total from $12 to $13.50.

The new amount is effective as of January 1; it also will apply to booked cruisers who prepaid gratuities for 2018 cruises. Windstar charges one standard daily amount for all passengers, including children. A 15 percent service charge is added to all bar bills.

In a statement, Windstar said the new pricing is "more in line with the rest of the cruise industry." It added, "We value our crew, and this will allow us to retain and continue to attract top talent."

Cruise Critic members on the Windstar forums seemed nonplussed about the change.

"The crews of Wind Star Cruises deserve every increased cent. I do not think $1.50 per person extra will make a dent in our pocketbooks," said Cruise Critic member Strenz. "The $12 fee has been that price for years, they well deserve an increase."

Cruise Critic member Griller added, "It certainly is a very, very tiny proportion of the total cost of a Windstar cruise. I wonder why they don't just include it in the cost of the cruise, and charge a little more."

Windstar is the third cruise line to raise gratuities in 2018. Royal Caribbean and Celebrity Cruises revealed a few weeks ago that they would increase their daily amounts, beginning January 2, 2018.
