It is an expensive and peaceful place, meant for worry-free and comfortable rest.
The resort is considered absolutely safe for visitors, but still do not neglect the simplest precautions: do not carry large sums of money and jewelry (leave them in the hotel safe), in crowded places keep an eye on your expensive gadgets (smartphone, camera, tablet), leaving the parking lot, take your things out of it and close the windows.
And be prepared that you cannot wear beachwear (swimsuits, swimming trunks, pareos) outside the beach in Viareggio. Violation of this law is punishable by a fine of 500 EUR.
