Re the jetty you asked about on the beach in front of the apartments. I think the Glass Bottom Boat trip goes from there..........
The only tiny bugbear we had (and its nothing really) is that the drinks were very much watered down in the pool bar at night watching the entertainment. Plus if you drink "branded spirits" and are fussy make sure you ask for "Smirnoff" vodka or whatever whiskey etc.......... as they tend to give you that cheap rocket fuel stuff that costs about 3 Euros a litre!
But I find that happens in a lot of resorts anyway, and to be honest it might be different now as I noticed quite a few guests complaining about it when we were there.
Such a small thing that it wont have an impact on your holiday but its just as well to be prepared!
There is internet access and some arcade games near Reception and just out the front on the beach is a volleyball net.
During the day there are loads of activities if you want to get involved, aqua aerobics, volleyball etc for both adults and kids..........my husband got extremely competitive in the waterpolo matches!
Have a ball........you are in a great complex!
