The Reunion House is part of The Block — four Mercer Stays homes on the same street in St. Charles, so large groups can stay together instead of scattered across town. Every home has its own hot tub.

🏟️ The Stadium by Mercer Stays — just 3 houses away · 4 BR / 3 BA · sleeps 12 · private 2.2-acre sports estate · lit basketball court, soccer field, batting cage, golf net, pickleball, disc golf · arcade room + billiards/ping pong/foosball game rooms · 8-person hot tub · an 8-minute walk to the Family Arena. The easiest way to add beds and space right next door.

Two more homes on the block:


🐾 The Getaway House by Mercer Stays · 4 BR · sleeps 12 · fully fenced, dog-friendly half-acre · detached game room · 4-person hot tub · outdoor basketball court
🌳 The Chalet by Mercer Stays · 2 BR / 1 BA · sleeps 5 · private 1.2 acres · 4-person hot tub lounge — ideal for a couple or smaller group traveling with the main party

Skip the cramped hotel suite and step into a newly renovated, locally-owned home built for getting everyone together. Part of the Mercer Stays collection of experiential homes in St. Charles, The Reunion House was handcrafted around your comfort — a very large, open floor plan with room to spread out, a private setting, and the kind of space that turns reunions, weddings, and group getaways into real time together. Just under 2,400 sq ft, comfortably sleeping up to 14.

Mercer Stays exists for one reason: to create spaces that naturally pull people back together. Experiential stays for your family.

⚡ Wi-Fi 1 Gbps + 3 extenders — reliable whole-home high-speed internet for streaming, gaming, video calls, and remote work. Spectrum TV Stream with 85+ channels. Password provided at check-in.

🛁 Private Outdoor Hot Tub — soak under the stars in our hot tub, comfortably seating 4, heated year-round with adjustable jets and ambient lighting. Towels provided.

🍳 Fully Equipped Kitchen — cook with ease: rice cooker, microwave, fridge, oven, dishwasher, baking sheets, mixing bowls and mixer, pots and pans, plates, cups, and silverware. Basics like oil, salt, and coffee/tea included — and if there`s something you need that we don`t have, tell us and we`ll have it delivered.

☀️ Expansive Back Porch — stretch out with 4 sun loungers and a shaded dining area for morning coffee, meals outside, or evening drinks. The space flows right to the hot tub, with outdoor lighting and a dining set for 6.

🎮 Game Room (in the garage) — air hockey, ping pong, double-shot basketball, skeeball, and classic arcade games (Pac-Man, NBA Jam, and arcade racing), plus a wet bar and TV. The spot for friendly competition after a day out.

🏀 Outdoor Basketball Court — for pickup games and shooting around.

📺 Smart TVs throughout — for shows, movies, and game-day viewing.

🍹 Wet Bar — mix up your favorite drinks.

🚗 Parking — private driveway for up to 4 vehicles. Please note St. Charles County does not permit street parking and the street is one-way in and out; these rules are enforced, so all vehicles park in the driveway.

🌳 Near the Parks — Webster Park is a 5-minute walk, with a playground, community building, and a loop trail linking to Heatherbrook Park. Wapelhorst Park is about 2 miles away (a 6–8 minute drive) with dog-friendly off-leash areas for playtime and morning strolls.

🏡 Accommodations

🛌 Bedroom 1 – Master King Ensuite: king bed, private balcony access, in-room safe, and private ensuite bath.

🛋️ Two comfortable pull-out couches in the living room.

A note on layout: all bedrooms are upstairs (five steps up from the living room). The home is private and restful — blackout-friendly tinted windows throughout keep things cool and comfortable during the day.

🎉 Made for gathering

Unwind on the front and the massive backyard patios, relax in the hot tub, or head to the game room for some friendly competition. With a fully equipped kitchen, room to spread out, and space for the whole group, The Reunion House is built for reunions, weddings, and getaways where everyone stays together. Guests enjoy full access to the entire home. Need even more space? The Stadium is just three houses away — see The Block at the top of this listing.
