The deal we got with Regent Seven Seas cruises from the UK to Miami included return business class flights where we have already reserved our seats on all flights with Delta.
It's on a new ship Grandeur of the seas. This includes pre night hotel in Miami, great cabin , drinks package wifi, all excursions, gratuities etc
The actual price of business class flights for both of us is about the same total as we payed for the whole package!🤔 so we are definitely not giving that up. Probably never get a deal like it again. TA said it's Regents responsibility as a package holiday to get us there & back if anything goes wrong it's them that have to sort it out. It's all in the t&c's.
