They will be sent an individual Flight Verification to complete so that their arrangements can be made.
Note: This is a courtesy request. The resort is not responsible nor obligated to comply with any of your requests. You are entirely responsible for personally managing any allergies, bringing any medication you need etc. for you and anyone you are in charge of. Prepare for this in advance. Resorts and supliers will try to be helpful and mindful but again are not resonsible for these types of things.
