I know this is probably silly to even ask....but I promised I would I'm going with a family group to Peru in May, spending 2 days at the end in Puno. One of my sisters has asked if there is any way she can go to Bolivia and return in one day. She doesn't care about WHERE in Bolivia she goes--just says it's on her "bucket list" to say she has stepped foot in Bolivia. (I told you it sas silly!)
Is this even possible??
