What is an all inclusive holiday?

it should mean that the family should get all day and all night drinks and meals or snacks during the day.i have recently returned from an all inclusive deal that was not in the same criteria as mentioned b4.the children had to wait til 4.30 for coffee and biscuits,(who gives a child coffee???) the bar shut at 10.30 at night which is a time when u just wanna chill and benefit from ur holiday deal ie get drunk for free.if u had a lie in n missed breakfast there was a wait until 1.30 for a lunch.so when i approached the management abiout this i was informed i had booked '' light all inclusive'' ive checked this online and cant find it out anywhere as to what this means.plus,i never got told this by the tour operator or when i type my holiday plans into my search engine,and of course there will never be a refund will there lol so pls double check the hotel b4 u pay
