No
No but you do need I.D.
If you have not been able to find travel insurance by going out and hunting for it, turn to the internet. Programs such as CAA Travel Insurance and Ontario Blue Cross have websites dedicated to getting you the help you need.
No, Belfast is in Northern Ireland which is part of the UK - you don't need a passport to travel from one part of the country to another.
There is not any direct rail connection between Belfast and France. You will need to travel via London, using ferry service. It will cost you $90 to travel from Belfast to London (ferry and train both), and another $117 to travel to Paris from London via train.
I think, no matter where you are going, if you are going to be gone on an expensive vacation, it is always worth it to get travel insurance. Bad things can happen at the last moment, and it would be nice to have your money back if need be.
Belfast is part of the UK. Technically you do not need any form of identification

Your auto insurance covers the trailer as well so there is no need for travel trailer insurance.
One does not need travel insurance to go to the supermarket. Travel insurance is only used when one is traveling out of the city, state, country, or continent.
