Keep each traveller's documents, tickets and confirmations together so everyone can access the required information at the airport and during the return journey.
Choose an arrival day that leaves room for a settled first evening rather than placing a major activity immediately after landing. A downtown stay offers a change of setting from the Strip and works well for travellers who want restaurants, entertainment and easier evening walks.

January and December bring daytime temperatures of 15 °C, with nights around 2 °C and 3 °C. These months suit a winter city break, especially for travellers who want to move between warm interiors, restaurants and shows with a light jacket for evenings.
March and November offer daytime highs of 22 °C and 21 °C, with nighttime temperatures of 7 °C. April and October are warmer, reaching 27 °C and 28 °C by day. These periods provide a balanced combination for sightseeing, evenings outdoors and a comfortable pace.
May through September brings summer heat, with July reaching 41 °C and August 40 °C. Late spring and early autumn are more comfortable for long walks and daytime activities, while summer also supports pools, evening entertainment and indoor attractions. Use the trip film to see how each day fits together.
Plan a lively three day Las Vegas visit
Begin with the Welcome sign and Las Vegas Boulevard, then continue toward the Strip landmarks that match your group's interests. A relaxed pace gives you room to pause for photos, cafés, street scenes and the transition from bright daylight to the illuminated evening atmosphere.
Place one major attraction or show in the middle of the day, followed by a quieter break before dinner. This rhythm keeps the short trip full without making every day feel hurried. You can drag stops between days and ask the plan checker to reorder the route after each change.
Finish with a final evening that reflects your group. A couple might choose dinner and a show, while families can devote time to interactive attractions. Dates are optional while planning, and you can add them later to place weekday, climate details and live booking information on each day card.

Build a fuller week beyond the Strip
For a week, use the first few days to explore the central Las Vegas experience, then add excursions that appeal to your group. The map makes it clear when your route stays in one area and when a new day deserves its own base. Balanced pacing supports two to three stops in many parts of the day.
Keep at least one day flexible after arrival and before departure. Use it for a spontaneous activity, a rest or a repeat of a favourite experience. This space is particularly useful for groups combining celebrations, shopping, shows and time with friends staying in different neighbourhoods.
A document vault keeps passports, tickets and confirmations connected to the trip, while a packing list reflects the selected month and climate. These tools give group members one place to review the essentials, add comments and vote on activities before the holiday begins.
Shape seven days with a balanced route
A seven day Las Vegas trip can begin with the Welcome sign, Las Vegas Boulevard and an evening around the Strip. On the next day, group the central attractions by area and leave an open block for dinner or a show. This creates a clear rhythm while giving you room to respond to the group.
Use the middle days for different experiences. One can focus on entertainment and interactive attractions, while another can cover shopping, dining or a calmer neighbourhood. The planner lets you replace a stop, move it to another day and select a relaxed or balanced pace as the shape of the week develops.
Reserve the final day for a flexible activity near your stay and a smooth departure. Climate cards help you prepare for daytime conditions, while live partner links keep flight, accommodation and activity choices in Canadian dollars. The door to door view connects your home in Ottawa, the airport journey, the flight and the transfer to your first stay.
Organize bookings and share the finished plan
The route from Ottawa to Las Vegas is displayed with the flight connection, transfer to your stay and daily movements in one map. Partner links show current prices for flights, stays, tours and transport in Canadian dollars, with a live price check where a current quote is not already displayed.
Use the trip budget to watch prices and split shared expenses among the group. You can share one link with viewing and editing roles, allowing companions to comment and vote. This approach keeps decisions attached to the itinerary instead of scattering them across separate conversations.
Canadian travellers can also use the Long Weekend planner when public holidays and leave days create an opportunity for a longer break. March break, summer vacation and Christmas break are useful planning periods to compare with regular weekends and choose the dates that suit everyone.
