A requiem for spur-of-the-moment travel

The days of spur-of-the-moment travel seem to be over. Booking air travel as a necessity and then hotel and ground transport as supplementary requirements, are no longer the only actions required to fly. Covid Health protocols and entry requirements have now leap-frogged over booking your air travel as a necessary first step. While many websites endeavour to assist travelers, the first step is to research the exit protocols from the country of your departure. Once you establish how to depart, you must research the entry protocols for your destination, aligned to your country of departure. This is because entry protocols may differ depending on the country of departure such as the entry protocols in the UK traffic-light based system. If you are transiting through one or more countries on your journey to your final destination, these steps must be repeated for each  transit country. Many of these exit and entry health protocols require testing and proof of negative Covid tests. These too must be timed carefully prior to your departure so that your swabbing and receipt of your test result remain valid at the time of your arrival at your destination. Is this sufficient to initiate a requiem for spur-of-the-moment travel? We mourn. Do you?
