Hi Linsey, same name as my daughter! opinion is always divided as to go independent or package, we nearly always go with Thompson, they offer 11days packages in Arillas, as we have already booked one for next September! we stay at the Mathraki, but they are adults only, I think, but you may be ok with A young child.
Kaloudis Village is at the end of the sea front on the left, and has everything you need, including a little shop, pool, bar and restaurant, as its on the flat, it would be easier for you with your daughter.
The Akti is good we have been told, and very central, does get some noise from the bars opposite at night(the Malibu and the Coconut). Hope you find something to suit your needs, we will be there on Monday!
