Travel to Wigmore
If you are coming by rail get off at 'Luton Parkway' and there is a TUI staff bus that runs every 20 mins, no ID is needed to get on and that will take you to Wigmore.
If flying into LTN then the TUI bus also goes to the terminal (You cant miss it as its big, blue and has TUI down the side.)
Or if your coming by car they may let you park in the visitors area, or theres the local shops or ASDA or the short stay car park at the terminal and jump on the TUI bus.
Hope that helps answer a few questions
