We bought Motorola T5200's from Amazon.com last year, [£90], from our home in Scotland - and had them shipped to our hotel in Orlando 1 week before we arrived. Went to the front desk on arrival and picked them up with no hassle - customer service at the hotel were very helpful.
The radios have 15 channels with 10 sub channels - and were a real bonus with 5 adults and 2 kids last year. We could split up/rest etc and keep in contact - especially when the women 'disappeared' deep into in the mall!!
