Just as planning a trip in July differs greatly from one in February, so can the price.
To see the most accurate price for your trip, add dates when searching for a place. Why? Because some Hosts have custom prices that override the default or minimum price for specific dates or time periods (including holidays, weekends, and week-long or month-long reservations).
If your Host updates the pricing for their place before you request the change, your new reservation will reflect this pricing.
