You could have multiple nodes running in different locations and connect to them remotely while you're travelling. But yeah, it's irritating if bitcoin core or lightning crashes while you're away and you can't physically access it to troubleshoot.

I'm not sure how best to deal with this securely. Also not sure how vulnerable self-hosted nodes are to DDOS attacks. Is this why people prefer to host their nodes on a server?
