Federal officials said it could take at least another day to open the main highway to Acapulco, which was hit by more than 13 landslides from surrounding hills, and to bring food and relief supplies into the city of more than 800,000 people.
Two of Mexico's largest airlines, Aeromexico and Interjet, began running flights to and from the still-swamped international airport.
Those with tickets got first priority, then families with small children or elderly members, officials said. Interjet's director Luis Jose Garza told Milenio TV that his airline's first flight was taking 150 passengers back to Mexico City and it hoped to run four to six such flights Tuesday.
The Guerrero state government said 40,000 tourists were stuck in the city, while the head of the local chamber of business owners said reports from hotels indicated the number could be as high as 60,000.
Many tourists finally emerged from their hotels Tuesday morning after days of pelting rain.
"We realized the extent of the disaster for the first time because we were closed in and only saw rain and flooding," said Alejandra Vadillo Martinez, a 24-year-old from Mexico City staying with seven relatives in the Crowne Plaza Hotel overlooking Acapulco's bay.
The main coastal boulevard was open Tuesday and most hotels appeared to have power, water and food. But that was little consolation to those unable to leave.
"We've realized that it was a mistake to come to Acapulco because all we saw was rain, rain, rain," said Guadalupe Hernandez, a 55-year-old housewife from the Mexican capital.
The situation was far more serious in the city's low-income periphery, where steep hills funnelled rainwater into neighbourhoods of cinderblock houses.
City officials said about 23,000 homes, mostly on Acapulco's outskirts, were without electricity and water. Stores were nearly emptied by residents who rushed to stock up on basic goods. Landslides and flooding damaged an unknown number of homes.
Natividad Gallegos said she returned Monday from shopping to find her house in a poor Acapulco neighbourhood buried by a landslide that killed six members of her family, including her two children. "I saw a lot of strangers with picks and shovels, digging where my house used to be," she said, weeping.
The coastal town of Coyuca de Benitez and beach resorts further west of Acapulco, including Ixtapa and Zihuatenejo, were cut off after a river washed out a bridge on the main coastal highway.
Marcela Higuera, who runs a bread stall in the Coyuca market, said the only aid that had arrived so far was a helicopter that rescued stranded flood victims.
"Flour's already run out. There isn't any in Coyuca," she said, adding that the Coyuca River had swept away the bridge and riverside restaurants, and flooded low-lying neighbourhoods. "This is the worst storm that I've seen."
"There are hundreds of people in shelters and they're begging for clothes and blankets because everything they have is wet," Higuera said. "They had to leave without taking anything."
Remnants of Manuel continued to drench Mexico further up the Pacific coast and the US National Hurricane Center said it could regain force near resorts at the tip of the Baja California Peninsula.
One of the biggest single death tolls was reported in the Gulf Coast state of Veracruz, where 12 people died when a landslide smashed into a bus traveling through the town of Altotonga, about 65 kilometres northwest of the state capital.
More than 23,000 people fled their homes in Veracruz state due to heavy rains spawned by Ingrid, and 9,000 went to emergency shelters. At least 20 highways and 12 bridges were damaged, the state's civil protection authority said.
