Re: spontaneous travel...
Always, I never plan holidays, just sit in car & go. Once decided a weekend trip to Newyork (from London) bought the ticket at airport & went for a weekend to Newyork. Flew to Pakistan out of blue while on spontaneious holidays in Istanbul .. my stories will never end of spontaneous travels.
Last one a motorbike trip from London to Amsterdam via (Calais) without any plans :D
