Thanks for your question, sounds like you have a great adventure planned.
Once a policy has been issued we are unable to add the snow sports and activities option to your Certificate of Insurance. This option is only available to you during the purchase process.
You have a couple of options. You can purchase one policy which includes the additional premium for this activity for the entire duration of your travel dates.
Alternatively, you can purchase two separate policies. One for the entire duration of your travel dates which does not include this premium, the second for snow sports and activities for the dates you know you will be participating in this activity.
Should you have any further questions please don’t hesitate to ask.
