Hahaha it's not one of the 'fabled' $500. I booked a trip and they messed it up, as they booked the wrong dates (confirmed the right dates but emailed confirmation of different ones) and the dates they booked were only part covered by free dining at the time so they offered the card as an apology! Unfortunately the trip wasn't one of the 'special' ones
Thanks for the advice re
Lego, looks like its far better for me to buy it online!!
