Worth remembering that by the time
you go next year Cyprus will have introduced the Euro & therefore prices may have gone up slightly

As is the case when other countries have joined everything gets rounded up
I always advise people to take enough spending money as if you were going out every evening/day at home in the UK as drinks are pretty comparable...albeit the measures are larger so you might not need as much

Being half board will save money though.
Spending money is a very emotive subject and one that gets asked an awful lot on the forums, but no 2 people are the same and so it can vary hugely between people as to what they do/expect to spend whilst on holiday.
I've been going to Cyprus for 20+ years and the advise above usually stands me in good stead as to what to take. If you plan to hire a car, do trips etc. then that needs seperating I think from "spending" money as these are extras IMO
