Plastic vs Glass for Outdoor Events: Park Rules and Safer Options

A wedding or reunion in a forest preserve shelter, a park pavilion or a backyard has a different glass problem than a ballroom: grass swallows shards, bare feet are common and animals and children wander through. Park rules can also settle the question for you.

Quick decision guide

What to check with the park or venue

Public parks and forest preserves set their own rules on glass, alcohol and what vendors can bring, and the rules differ by district and site. Before you plan:

• Ask for the glass and container policy in writing. Many public beaches and parks ban glass bottles; your site may too.
• Ask about alcohol. Chicago Park District's published FAQ says alcohol service is allowed only at its Special Event Venues, through caterers on its list, with insurance. Other districts have different rules. See Illinois alcohol rules for private events.
• Ask about permits and tents. The same FAQ says tents over 240 square feet need a City of Chicago building permit and must go through the park district's preferred professionals. Check this with your district, and read our Seasons and Venues guides for more on venue rules.
• Ask about cleanup and trash rules, since broken glass and plastic both create work.

Comparing the options

Acrylic stemware is a rental category for many companies and looks like crystal at a distance. Wine and champagne in acrylic loses some aroma and feel, but guests rarely mind outdoors. If you want real glass for the toast only, keep it for a controlled moment, such as seated guests in a tent with a floor, then switch to acrylic for the party.

Wind, grass and heat

A stemmed glass on grass tips easily and spikes into soft ground. Stemless acrylic is more stable. A glass left in the sun turns drinks warm quickly, while an insulated tumbler stays cold longer. Water and cocktails in clear acrylic can show condensation, but it will not shatter if dropped.

For tent events, add a floor if you want glass: check the forecast a week out and again the day before. If your site is a lawn, use level chair footing and consider acrylic for the whole bar.

What guests notice

Guests care less about the material than about the experience. They notice a glass that tips on uneven ground, a cup that feels flimsy or a warm drink. They rarely notice that a stemless acrylic tumbler is not crystal. If you want a premium look, spend on the details guests see: a clean garnish, a cold drink, a printed menu and a tidy bar. In a Chicago summer, a cold drink in a sturdy cup beats a beautiful glass that has to be replaced twice.

Also think about the end of the night. Plastic cups blow across a park and become litter, and parks may hold you responsible for cleanup. Ask your rental company about racks for acrylic, since many companies wash and rack it the same way as glass. Compostable cups only help if the venue actually composts them, so ask before you pay extra.

Safety checklist

Counting outdoors

Count outdoor glasses a bit higher, since guests put them down and forget them in a bigger space. See how many glasses per guest. A water station keeps people hydrated in the sun; see water station ideas. Pair acrylic with a light, sturdy seat: garden folding chairs and rattan garden chairs suit grass and gravel.
