Hello. I would like to advise you on a very good and reliable website that is really worth checking out. Here is the link for you https://www.globelink.co.uk/general-information/extensions/adventure-activities/. They will help you to get insurance very favourably.

I completely agree that the insurance quote consists of a huge number of factors and it is not always possible or convenient to calculate it yourself. But running through insurance companies in this century is somehow strange. Just upload your data to this aggregator site and you will be shown the appropriate options. And you only have to choose the most appropriate of them. For me, it is very convenient.

It seems to me that you can't do it on your own. There are too many factors to consider, and we can't take them all into account. And you won't be able to give such information on the forum. So just go to a couple of insurance companies and compare the conditions.
