Hotel Tips:  You may want to keep the all-night racket in nearby Disco joints in mind if you like to sleep undisturbed.... The town is small and no matter which hotel you choose you'll hear the racket from the Discos when they're in operation.. Unless your planning to party all night, do yourself a favor and choose a hotel not located next door to Disco joints.. (preferable with air conditioning as the noise from the compressor tends to help drown the noise out)
