It's spring break, which means there are a lot more children and parents in parts of the Houston area than normal.
This will be the first spring break since Galveston's Pleasure Pier opened last year, and this week's sunny weather should help it and the island do a booming business.
Even on a windy, cool day, there are few complaints among the thousands along the beach and seawall.
"Hey it's great. It beats Missouri," visitor Amanda Frech said.
This week is very important for Galveston businesses. Between 300,000 and 500,000 visitors are expected, and that means a lot of money.
"As an example last year at this time, $4.2 million came in during just one week," said Yvette Wilhelm with Galveston Visitor's Bureau.
Galveston is not alone. The museums and zoo areas have been packed.
Mayor Annise Parker's office estimated 350,000 people will pass through the Hermann Park area each day.
A Houston Police Department traffic command center has been set up to watch real-time traffic cameras to keep bottlenecks to a minimum.
"Our the best advice, from those who know the families, is to plan ahead and allow plenty of time," said Todd Holloman, an administrative coordinator with the Houston Mayor's Office.
