Ah, the twin bed nightmare! Gay friendly accommodation means a warm and friendly welcome to gay and lesbian guests, usually located close to gay bars, gay saunas and gay clubs.
When booking accommodation, know what you want before booking, make it clear to the hotel, guesthouse or accommodation owner and this way you're more likely to end up with the perfect gay friendly accommodation venue for you! There's always a bit of luck involved if you're visiting an area for the first time.
Some gay friendly guesthouses may be exclusively gay, some gay friendly welcoming all. Check out 'Gay Times. Great Britain and Ireland', by John Szponarski for some useful tips or the Spartacus International Gay Guide. Also see 'www.gaytimestravel.co.uk' for superb tips and advice on gay travel (mostly going abroad though).
