Thanks guys and girls.
so far i've discovered that live-boards tend to have the need for PADI already, so for the open water course it has to be hotel based.
i will defo go life-board on the next hols.
Can't be asked to do the pool bit here as it will work out more £ in the long run.
i have dived 4 times in the Caribbean, but the regulations there were not so strict so i went down well below 20m and even the PADI open water is 18m max. It is a shock to discover that

.
Once i digest it all and have ALL the info inc prices i let you all know the details
