After you purchase you can go into the cruise planner. If you click on internet it will show that you already purchased it. However, you can also see the current price. If it is lower you can cancel then repurchase. You could still catch a Memorial Day, July 4th, or Labor Day sale.
Yes both devices can be connected at the same time.
As for pricing, you come out to $27.99 per day. On my Odyssey cruise, 8 days, I bought the Voyage package for one device for $15.99 per day (total $127.92) during the black Friday sale. Buying on the ship it would have been $24.99 per day and would have cost me $149.94 with my D+ discount. Sorry I don't recall the price for 2 devices.
When do you sail? If any holidays come up before your sailing I'd keep an eye on your cruise planner pricing.
So you think it is OK to not acknowledge the gifter with a thank you? Yet I feel the need to thank someone for providing a service to me even if they are being paid to provide that service.
I think of a perk as something given to me by a company as a thank you, as in thank you for being a long time customer. I hardly consider something that I've been paying for....cabin service, food, etc. to be a perk.
The same virus that almost did in the travel industry now seems to be their golden lifeline for what ever cut backs they care to make.Reduce staff, reduce service, reduce food choices, reduce food amounts, etc. Just blame covid for [insert cutback of your choice here] and people just back down.
