Yes. Outside July and August, most Montenegro activities can be booked for the next day and many for the same morning — group boat trips, kayaking, city walls tours, tastings and paragliding usually hold next-day availability. Full-day trips with transfers (Tara rafting, Durmitor, Mostar) need booking by around 18:00 the day before because pickups start at dawn. In July and August, private boats, Nevidio canyoning and private tours often sell out 3–7 days ahead. On BookNRoll bookings are confirmed instantly and cancellation is free up to 24 hours before: https://booknroll.com/explore.
Weather is the usual reason people book late — and because cancellation is free up to 24 hours before, booking two days out costs nothing even if plans change.
Same-day requests are possible: message the guide directly through the platform and they confirm availability, usually within the hour during the season.
