Insider Tips for a Smooth Long Weekend

A little planning goes a long way over a busy holiday. Here are a few local pointers to keep your trip stress-free:

• Arrive early at the lakes. Popular parks like 370 Lakeside fill up fast on holiday mornings, so aim to claim your picnic spot before mid-morning.
• Pack for sun and water. Late summer heat is real, so bring sunscreen, refillable water bottles, and a change of clothes for the splash park.
• Book your stay ahead. Labor Day is one of the busiest travel weekends of the year, and the best family homes go quickly. Reserving early gives you the most choice.
• Plan one flexible day. Leave an afternoon open for spontaneous discoveries, whether that is an ice cream run on Main Street or an extra lap around the lake.
