5 Must-Have Features in an Activity Reservation App for 2025
Guests today expect booking a tour to be as simple as ordering dinner or reserving a rideshare. If your booking process feels complicated or outdated, potential customers will move on quickly. That’s why choosing the right activity reservation app matters more than ever in 2025.
Resmark was built specifically for tour operators, combining all the tools you need to manage reservations, payments, waivers, and marketing in one place. Here are five features that set it apart and why they should be at the top of your list when evaluating booking technology.
1. 24/7 Online Booking That Never Misses a Sale
Guests want the freedom to book on their own schedule, not just during office hours. With Resmark’s embeddable booking widgets, you can capture new customers directly from your website anytime, day or night.
Key benefits include:
- A user-friendly checkout experience that reduces abandoned bookings
- Optimized mobile booking so guests can reserve from any device
- Multi-activity booking and add-ons so customers can build their perfect itinerary in one cart
With real-time availability built in, your guests always see accurate openings down to the second. That means no overbooking headaches for you, and no disappointment for them.
2. Automation That Turns Leads Into Customers
Resmark isn’t just a checkout tool. It also helps you grow by capturing and nurturing leads. Using custom forms, you can gather contact information from people who aren’t quite ready to book. From there, Resmark’s automated email sequences follow up with them - reminding, encouraging, and guiding them back to complete their reservation.
This automation doesn’t stop after booking. Resmark sends confirmation emails, pre-trip reminders, and even review requests once the activity is done. All of it happens automatically, so you spend less time chasing guests and more time running your business.

3. Built-In Digital Waivers for a Seamless Guest Experience
One of the biggest frustrations for both guests and operators is the waiver process. Resmark solves this by including WaiverSign, a powerful digital waiver system, right inside the platform.
Here’s how it helps:
- Guests automatically receive a waiver link when they book
- Waivers can be signed on desktop, mobile, kiosk, or even by scanning a QR code
- Manifests update in real time, so staff instantly know who has signed and who hasn’t
This saves time at check-in, reduces paperwork, and ensures you always have the documentation you need.

4. Powerful Back-Office Management
Behind the scenes, Resmark gives operators the tools they need to manage every aspect of bookings. From inventory control to financial tracking, you have full visibility into your business.
Some highlights:
- A real-time dashboard showing upcoming tours, cancellations, and overdue payments
- Custom tour manifests that display exactly the data you need
- Auto inventory generation to ensure you always have capacity to sell
- Flexible payment options, including deposits, balances, and gift cards
- Task management and booking notes to keep your team on the same page
Instead of piecing together multiple tools, Resmark puts everything under one roof, saving you hours of admin work each week.
5. Expanded Sales Through Partnerships and Channels
Empty seats are lost revenue. Resmark helps you maximize every opportunity by making it easy to connect with resellers, travel agents, and OTAs.
You can:
- Share real-time inventory with partners so they can sell your tours directly
- Set unique pricing per channel to control commissions and margins
- Automatically generate invoices and statements for resellers
- Integrate with platforms like Viator, GetYourGuide, Expedia, and TripAdvisor
By opening your tours to more sales channels while keeping control of your inventory and pricing, you’ll fill more spots without creating more work.
