Hi MeTarzan,
Welcome to the DIS. I think it would be best
to get them before you go. I have not heard
of 2 way radio's for rent.
I not sure about the brand to get, but I do
know to get the ones with the 14 channel
and the 38 sub channels. Alot of people at
the parks have these so the sub channels
are needed to try and get privacy.
We have cobra and like them but there are
alot of other good brands. I did see a good
deal at Sam's Club the other day. You got
2 radios w/subchannels, rechargable
batteries and charger, and some other
stuff for about $ 68.00. Have a great
time.
