If it fails, what protects us? Asserting that the duration of the trip defines the low season for budget reasons is a dangerous simplification that ignores major risk factors. The link between a fixed duration and cost optimization is too rigid, because even in low season, unforeseen local events can cause prices to spike. Limiting the duration does not guarantee the absence of these tariff peaks; it is a false safeguard. For example, in Japan, a sudden neighborhood festival can make a two-week stay more expensive than a longer period with careful planning. True caution would be to check specific local calendars and event forecasts for the threshold of financial non-return.
