If your need to recharge would best be served by staying nearby and planning outings and meals with your hosts, then – you should do that. (Wouldn’t you accept this from your own guests? Of course you would!) These frequent visits with your friends are lengthy and sound like a lot of fun, but I do think it’s not only acceptable, but advisable, for you to be honest about your own needs.
I have a theory that the experience of the lengthy pandemic awakened in many the need – or desire – for more solitude.
