NEW YORK ( TheStreet) -- Vacationers are looking for warmth and sunny skies as cities located in the world's more temperate zones dominated Priceline.com's ( PCLN) annual list of the 10 most popular travel destinations for 2015.
Topping the list for the United States were two disparate locales, Mickey Mouse's Orlando, Fla., and Sin City, Las Vegas. Oahu, Hawaii, made the Priceline list for the first time joining long-time favorite destinations, including New York City, New Orleans and Atlanta.

"Within the U.S., Las Vegas continues to be a hot spot in the New Year, followed by New Orleans, Miami and Fort Lauderdale -- all three cities flew to the top of this year's list of places to visit," said Priceline.com travel editor Brian Ek.
International travelers decided to head to new locations for the coming year, with only Toronto being a repeat for the top 10 list.
"If interested in traveling abroad, must-visit international destinations include Cancun, Cozumel, Costa Rica and Los Cabos, demonstrating that Latin America is a trendy travel hot spot for 2015," Ek said.
For those looking for a bargain, Priceline.com also revealed the 15 most affordable destinations in the United States, based on advanced hotel reservations. Dallas and Salt Lake City were the least expensive with daily rates in the $87 range, while Denver and Portland, Ore., were at the other end of the price spectrum coming in at just over $109.
While deals are to be had for hotels, lower oil prices have not had any impact on airfares. Sen. Charles Schumer (D-N.Y.) earlier this week called for an investigation into why air travel has not enjoyed a price break.
"At a time when the cost of fuel is plummeting and profits are rising, it is curious and confounding that ticket prices are sky-high and defying economic gravity," Schumer said. "The industry often raises prices in a flash when oil prices spike, yet they appear not to be adjusting for the historic decline in the cost of fuel; ticket prices should not shoot up like a rocket and come down like a feather."
