From their website so I don't think so:
Security Procedures
Busch Gardens has increased security procedures, which may result in slight delays while entering the park. As a part of this process:
All bags, backpacks and packages are subject to inspection prior to entering the park.
As a reminder, the following items are not permitted to be brought into Busch Gardens for the safety of our animals and our guests: weapons, knives, any other type of sharp objects, straws, large hard or soft coolers and any hazardous items or materials.
Please leave any unnecessary articles secured within your vehicle to expedite your entry into the park.
Busch Gardens is not responsible for fire, theft, damage or loss of vehicle including articles left within.
