Just come back from KOS, stayed at Sunshine Apartments in Tingaki, and what an excellent resort. A few tips however:
Use Theokritos Travel, owners are English and offer excellent advice and VFM on all excursions, currently offering buy 2 get 1 free deal.
We went to Paradise Beach, Greek Night, Cruise and Nissyros to the Volcano, all great trips.
There are ATM's and all work OK, alot easier than taking Travellers Cheques.
No problem with Mossies although very hot
The resort is great, lots of Tavernas, good cocktail bars, no nightclubs, worth going into KOS town, will cost 1.6 Euros each on bus and 16E in a Taxi .
Try the Australian bar on the front, good beer and Colin (CJ)is a friendly guy.
Cheers
Steve
