Has anyone actually been to London and tried using the 7 day travelcard with the National Rails double-arrow symbol on it for the Days out guide 2for1 offers? I've planned a trip for a group using numerous 2for1 offers and really need to know if this still works. There has been some indication on travel blogs that this may not work anymore.
I know on the daysout website it says valid with monthly or yearly travelcards. Yes, I have read some other postings about this subject but do not recall seeing a definitive response from someone who has actually tried this.
