The waterpark is Faliraki Sooze so if you're heading there you'll need to get the bus or a taxi to Rhodes Town after.

Just check reviews before you book as some of the cheaper hotels in town can be a bit grubby - not all though, i'm a big fan of Al's and The Alexia. Which hotel are you thinking of booking?

Don't know if there's any real tips to share, it all comes down to personal interest. I tend to head into the Old Town at night for the atmosphere and a lovely meal at Romeo's Garden, then i'll walk up to Orfandinou Street (Bar St) with a stop at The Blue Lagoon and Boudoir Bar en route, to party the night away :cheers. I guess a major tip in Rhodes Town is to check the prices before you stop for a drink or something to eat in the Old Town or Mandraki Harbour, there is the odd tourist trap with silly prices about.
