Austin River Float Trips Party Bus Rental

First-party planning ranges on this site still list San Marcos at about 32 miles and 35 minutes from Austin off-peak. That is a planning range, not a Saturday promise. The useful pin is San Marcos City Park. Lions Club Tube Rental’s site is built around all-day tube-and-shuttle service: last new tubes at 5:00 PM, last shuttle at 6:30. Listings place that window at 170 Charles Austin Drive. Recheck the shop before treating those times as a hold.

The Meadows Center lists 201 San Marcos Springs Drive for glass-bottom boat and education time on Spring Lake. That is the headwaters campus, not the tube chute. San Marcos’s single-use beverage container ban took effect May 1, 2024: reusable drink containers only on the river, banks, and marked No Zones; one cooler smaller than 30 quarts per person there; cans and disposable bottles only in marked Go Zones. Pack the bus cooler for that ordinance, then recheck the city page.

This site still lists New Braunfels at about 50 miles and 50 minutes, and Gruene at about 52 miles. The city’s River Operations page describes the Comal as about 2.5 miles long — the shortest navigable river in Texas — beginning at Comal Springs, asks visitors not to enter the water near those springs in Landa Park, and cites about a quarter million river users each summer. That is a city season figure, not a ranking.

“What Can I Bring?” is the city-limit rule sheet: no disposable food or drink containers; one cooler per person, 30 quarts or smaller, with a locking or latch lid; two tubes per person. On the Comal, flotation devices cannot exceed five feet, so most double tubes are not allowed; double tubes are permitted on the Guadalupe. Chapter 86.14 covers the Comal and the Guadalupe stretch inside New Braunfels. Rockin’ R lists shops on both rivers, including Historic Gruene. Write the shop and the river. A Gruene Hall stop after take-out is a second curb, not a substitute for the tube-shop address.

Tube Haus lists 12454 FM 306, Canyon Lake, TX 78133, and describes itself as a Guadalupe Horseshoe Loop outfitter open March through September, 9:00 AM–7:00 PM. Recheck those hours for the season you are booking. The shop is near New Braunfels; it is not inside the New Braunfels city-limit can-ban. Treating Canyon Lake as “the New Braunfels float” can send the vehicle to the wrong ordinance and the wrong last-shuttle clock.

A Horseshoe Loop day usually runs longer than a Comal city loop. The charter has to cover the extra I-35 and FM 306 minutes, the shop’s own shuttle pattern, and a group that may be farther from food when it climbs out. If the written quote is built on a 50-minute New Braunfels pin, a Canyon Lake take-out will blow the window. Name Canyon Lake and the shop, not just “Guadalupe.”

Outfitters move tubes between put-in and take-out. Austin Party Ride moves the group from the pickup city to the shop and back. Those are two vehicles. The charter should not idle in a tube-chute lane or chase a scattered take-out unless the written quote names a legal staging point.

Ask the shop whether their shuttle is included and where it loads. Then tell us whether the bus waits, leaves and returns, or stays with gear at the shop. This site’s checklist still uses 30–45 minutes of buffer for river delays and regrouping. That is organizer advice, not a timed study. Build the buffer into the hours you request.

A vehicle that technically seats the headcount can still fail once towels, dry bags, and one cooler per person are on the floor. San Marcos and New Braunfels both cap river coolers around 30 quarts; that is small on the water and bulky in an aisle. If the vehicle has wet-gear rules, the group should know before sunscreen goes on. Confirm usable capacity and cleaning terms on the written quote. Category photos do not prove the assigned unit.
