If you would like to make minor changes to your confirmed booking (date, time, number of guests, etc), we suggest that you reach out to the owner first. If the owner agrees to your changes, then either you or the owner would just need to notify GetMyBoat so we could update the details.
If there are major changes to the booking that require a change in pricing, GetMyBoat would have to adjust the pricing manually and either charge your credit card for additional / new charges or partially refund you if there's a decrease in pricing.
In either case, an email should be sufficient to notify us of any changes. You can email us at firstname.lastname@example.org.
