Wow! (actually I misstyped this as "Woe" 1st)
My DH & I and 3 other couples fell victim to ecruise dot com out of Lake Mary FL in 2009, after choosing that agency via the cruise compete website. We paid for our cruise in full at the outset due to special incentives for doing so, and ignorantly thought nothing of the fact that the payment (less deposit) was charged to ecruise not Celebrity. Several months later ecruise filed bankruptcy. We were very fortunate that ecruise had actually brokered our bookings through a brick/mortar agency, that our chase visa refunded the monies paid to ecruise and that our booking for the cruise was intact.
Since that time, we have booked 14 cruises via Costco Travel and 1 via Crucon.
Hard lesson to learn!
