There is no need to tip everybody, usually the barman and if you want to have sun beds reserved tip the person who does them.
Tip them every day or two not every visit and usually somewhere about 1 - 4 dinar (less than 50p - Ãƒâ€šÃ‚Â£2) depending on the frequency you use them and the service they provide, for example if I was using the bar several times I would tip the barman 5 dinar every other day which is about Ãƒâ€šÃ‚Â£2.20.
Tip the bellboys a couple of dinar only when you use them. It is also worth tipping the waiter / waitress in the restaurant if you get good service, do this at the end of your stay.
Don't fall in to the trap of tipping everybody all the time as the cost would soon mount up.
