SH 146, north and south
One road, two completely different trips.
South, SH 146 crosses the bridge over the Clear Lake channel into Kemah in a few minutes, except on a summer Saturday evening, when boardwalk traffic backs up onto the bridge approach and those few minutes become twenty. North, it runs through La Porte past the Bayport industrial area toward the Fred Hartman Bridge and Baytown.
The port terminals and plants north of town put heavy trucks on that stretch, and shift-change hours slow it noticeably toward La Porte. For Houston itself, most routes cut west on NASA Parkway to I-45 instead. Typical ranges from central Seabrook:
- Kemah Boardwalk: 5 to 10 minutes
- Space Center Houston: 10 to 15 minutes
- Hobby Airport (HOU): 25 to 35 minutes
- Baytown, over the Fred Hartman Bridge: 25 to 35 minutes
- Downtown Houston and NRG Park: 35 to 50 minutes
- Galveston: 40 to 55 minutes
- Bush Intercontinental (IAH): 50 to 70 minutes
Loading at a marina
The lots here were laid out for trucks pulling boat trailers, which is not the same shape as a 40-foot bus.
Seabrook's marinas and yacht clubs, Lakewood Yacht Club among them, sit along the water near the channel and down toward Clear Lake. Many have gated entries, and a club event may need the host to put your vehicle on a list before it arrives. Ask the marina office where a bus can load, then send the gate instructions to the driver well ahead of the day.
Dock times are the other master here. A sunset charter or a regatta party leaves when the boat leaves, so the pickup should reach the marina 20 to 30 minutes early rather than on the hour. For the return, set the time for when the boat is tied up and everyone is ashore, which is not the same moment as the scheduled end of the sail, and keep one person's phone answered for the driver.
The boat leaves when the boat leaves. Nothing about that is negotiable.

Stopping for shrimp on the way home
The markets near the water sell Gulf shrimp, crab and fish by the pound, and live crawfish in season, and a stop on the way back is easy to slot in.
Raw seafood inside a passenger vehicle does want a little thought, though. Sealed coolers packed with ice, kept in the luggage area, and a question asked before the trip about whether the vehicle you are quoted allows it at all. Much better to have that conversation in advance than at the counter with forty pounds of shrimp.
For a backyard boil the timing usually works better reversed: buy the seafood in the morning in your own car, and book the vehicle for the evening so the guests coming from Houston can enjoy the party and still get home. Our crawfish boil page covers the season and the group logistics, and the packing checklist handles ice, coolers and the napkins everyone forgets.
Wind, tide and the low roads
Some roads here flood without any rain falling on them at all.
Seabrook has taken serious storm damage before, most memorably from Hurricane Ike in 2008, and streets close to the water still take water in heavy rain or when a strong south wind pushes tide up into the bay. Hurricane season runs June through November. For anything on the water in late summer or early fall, have an indoor backup and agree with the host, in advance, who makes the weather call and when.
The day before matters more than the week before. Check the forecast and any coastal flood advisories, and if the waterfront road to your pickup looks likely to take water, move the meeting point up to SH 146, which sits higher. The weather checker shows what a given month usually brings.
How big, how long
Small, on both counts, more often than people expect.
Among Houston inquiries naming a party bus with a group size on file, about 20% were for ten or fewer and about 57% for 11 to 20. A Seabrook evening tends to be short hops between a marina, a restaurant and the Kemah waterfront, and on those streets the smallest vehicle that fits everyone is almost always the right answer. Ten people ride comfortably in the 10 passenger limo sprinter, which goes wherever a car goes. Eighteen have room to move in the 20 passenger party bus.
About 53% of Houston requests with a duration on file asked for three to four hours, and an evening spent between here and Kemah with dinner and a sunset rarely needs more than that. Add the island or a stop in Houston and you are asking for five. Next door, NASA Area and Clear Lake has its own page for space centre visits and business travel.
A big bus on a narrow waterfront street is a parking problem with music.
