Flexibility is key when booking a last-minute vacation package. Since availability can be limited, being open to different travel dates, destinations, or accommodation types can help you find the best deals. The more flexible you are, the more likely you are to score a great bargain. 

With last-minute vacation packages, you can often depart within days, or even the same day, depending on availability. These deals are designed for spontaneous travelers, so once you book, your confirmation and travel details will be sent to you promptly, allowing for quick departures. 

Yes, last-minute vacation packages are available for groups, whether you're traveling with friends, family, or colleagues. However, availability may be limited for larger groups, so it's best to book as soon as possible to secure enough accommodations and transport for everyone. 

Generally, last-minute vacation packages are non-refundable due to their discounted nature and short booking window. Be sure to review the cancellation policy before booking. If flexibility is important, consider purchasing travel insurance that covers cancellations or rescheduling.
