Some notes about the walkie talkies.
- The ship is made of metal. That will cut down heavily on the reception range. Also keep in mind the ship is long, so if you're at the adult pool on Deck 9(which is forward), and your cabin is aft on deck 5, you're not going to have very good reception, distance is distance, vertical or horizontal. Translation: the 2 milers have iffy range, the 5 mile ones will work better.
- Subchannels, subchannels, subchannels. Do not, under any circumstances get or bring ones that do not have this feature, or all you will hear is everyone who has one on the ship talking at once. Learn how to set the channel and subchannel, as you may need to switch them to find a combination that isn't too busy. Now what I mean by this; no you won't hear other people talking, but they are still broadcasting on the same channel as you, the subchannel just sets it up so you only hear from other radios set to the same subchannel.
- There are a lot of places those radios are disturbing; use them with courtesy for others, places like at dinner or the shows are a big no-no for them. Just during the day for them is fine in most places.
