Not done either of those but have done day island trip (twice) and enjoyed it.
Tip, Carole & Tayfun have a really big boat that is used for weddings, it is really nice as so spacious
and "open". thing is you need to find out when it is not being used for a wedding, book your island trip
that day and be absolutley insistent and bloody minded that you wont go if you are not on that boat! Not thast
they will lie, just their english suddenly becomes very poor
