Keep the original purpose
Consider what you wanted from the walk: distance from exhibition crowds, movement, food or an impression of the city. That determines the alternative. For quiet, a short pause in a suitable indoor space may be enough; for dinner, look specifically for an appropriate place that is open.
Do not automatically recreate the same route by taking taxis between every point. That can demand more organisation than the original walk. A smaller plan with fewer changes often suits the end of a working day better when the weather is poor.
Check what nearby means in practice
A venue may look close on a map yet have an exposed or awkward approach. Check the actual foot route, crossings and entrance. An apparently short connection through a building complex is useful only if it is open and publicly accessible.
If needed, ask reception for a specific route suggestion without treating it as a guarantee of opening hours. Check the chosen venue directly. A small gallery, cafe or restaurant should not turn out to be closed only after you have made your way there in the rain.
Create a real finish even if you stay in
If you remain at the hotel, make a visible separation between work and free time. Put stand documents away, charge the equipment you need and prepare tomorrow’s clothes. Then deliberately choose something that is not simply another sequence of business messages.
Using the lobby only makes sense if it is permitted and comfortable for you. You do not have to work in your room all evening because the outdoor plan fell through. Save the walk for another day and stop replanning. An alternative succeeds when it meets your actual needs, not when it becomes as extensive as the original itinerary.
