I need to talk about Avanti insurance and your cruise. If you have a disability and change any criteria like the possibility of having an operation at any time, their underwriters remove the cover of the insurance without any further ado.
So, if you have spent a thousand pounds on this insurance, it then becomes completely worthless. You have zero insurance cover on your holiday trip for the entire year. This is the level of cover by Avanti to anyone with a disability, because they clearly have little remorse and are total scumbags.
