10. Bring in a pet

There are plenty of animals at Disney’s parks – furry ones, such as Mickey Mouse and Pluto. There are even real animals at Disney’s Animal Kingdom.

Unless you have a service animal, you won’t be allowed to add to their number.  You can bring a cat or dog to the parks - but you'll have to leave it in a kennel.

9. Bring in a huge picnic hamper

Many guests seem to be under the false impression that they are not allowed to bring any outside food or drink into Disney parks. That is an urban myth – you can bring in sandwiches, drinks, snacks and just about anything else you fancy.

What you can’t do, however, is bring in an enormous picnic hamper. No coolers, boxes or bags larger than 24” x 15” x 18” are allowed.

The rules are stricter at Disney’s Animal Kingdom, which doesn’t allow any coolers at all (except for medical pruposes). Juice boxes with plastic straws are also prohibited, in case the animals get hold of the straws.

8.  Queue jump without FastPass

Disney asks that you don’t “bump into, push or move ahead of others” in queues for its rides and shows. Your entire party is expected to wait together, and members of a party are not allowed to join those already in the queue (again, this is another rule we see broken all the time).

7. Smoke outside designated areas

There was a time when Disneyland had its very own tobacco shop, right on Main Street, USA. Those days are long gone. Tobacco is no longer sold in the parks, and if you want to smoke you’ll have to do so in one of a limited number of designated areas (unless you're at Disneyland Paris, where we've found that many Cast Members seem to allow guests to smoke just about anywhere).

6. Sell stuff

Thinking of undercutting Disney’s prices by selling your own food and drink? Or offering any other kind of service? You’re unlikely to be allowed to operate for long on Disney property.

5. Bring in dangerous or hazardous materials

We know, we know – you probably haven’t got any plutonium stashed in your bag. But if you do have any dangerous materials on your person, they’ll be removed at the park’s security checks.

4. Hand out flyers or demonstrate

The distribution of printed materials of any kind is banned at Disney parks, so they’re not such a great place to promote your cause. Similarly, if you want to march, demonstrate or give a speech, Cast Members will be quick to stop you.

3. Display a flag or banner

This is one rule we suspect is not always enforced – particularly on Independence Day. But Disney asks that you do not display “any flag, banner or other emblem”.

2. Wear an adult costume

It can be tempting to dress up as a Disney princess or character during your visit. But do that, and you're liable not to be allowed into the park (unless you are aged under 10).

Of course, there's a fine line between an outfit and a costume...but Disney bans anything that can be viewed as a costume. So those princess Halloween outfits are out...unless you're attending Mickey's Not So Scary Halloween Party, when the rules are relaxed.

1. Wear offensive clothing

Bought yourself a clever t-shirt with a slogan on it from an online store? Think twice before wearing it to a Disney park. Clothing that is “excessively torn”, or items such as g-strings and bikini bottoms, are also out.

Some Cast Members may judge "offensiveness" levels differently, but anything that is even remotely liable to cause offence to another guest could get you thrown out.

Having said that, we recently witnessed a guest at Disneyland Paris sporting a “Sex lessons – free trials available” t-shirt, so it seems that this is one rule that isn’t always strictly enforced.
