We have used Luggage Free and are using them again for the upcoming Voyager cruise starting Istanbul and continuing through the Med to Ft, Lauderdal. We have used IPs Regent's suggested firm. While both delivered, Luggage Free wraps the bags in plastic to protect them. IPS Delivered bags in Sydney last year to the wrong port agent, even though they are Regent's partner. It was only through the efforts of Mariners crew that they were found in time and delivered before we sailed.
Shipping bags in the only way to go when faced with clothes for a long cruise!
