I've seen some threads from back in 2013 that said even if you did Online check-in for your room that you still needed to physically check-in at your hotel's front desk when you arrived to ensure that your DDP was active on your Magic Bands. It's now almost 2018 and I can't find any additional, updated information on this issue. Do you still need to physically see the front desk when you arrive or does your Online Check-in now truly activate your DDP on your Magic Bands?
