Logging in with no internet or wifi?

I'm in Ireland. Tomorrow I am going to my holiday home which Is a cottage on a remote Atlantic island. There is no mobile phone signal and no wifi or Internet. I'll be there for a week. I don't want to lose my streak, and would like to be able to log every day. I will get to the mainland a couple of time to check-in but not every day. Is there any way round this problem?
