ok lets be fair every one has there idea of a great holiday.depending who you are age wise.
you could just do the normal sunbathing drinking relaxing.not sure how long you are out for and resort yet.
but do try to get out of the resort your in at least one day and night.
so you could either nip over to playa den bossa around 4pm for the beach bars
go to ibizatown port area one night to sample the atmosphere.(bars shops)
easy to get a bus to any resort once we know where you are staying,( i will pm you).
you can get ferry boats as well to other resorts.thats nice.
sample the local food(not just kfc).
my be one night sort out a visit to the sunset bars in san an.
always slap loads of suncream on drink plenty of water in day not just beer
don;t show your goods when sunbathing(radio/phone ect) and put bags under bed or cover up well..get a safe in hotel you in
get a good mozzie cream or spray
only carry small amounts of cash with you.if you have a card put it somewhere esle on you.but take a card as a backup.if lack of cash
make sure you get insurance and have a European Health Insurance Card.you can do that online.easy enough and its free.
if your hotel does any trips price it up see if its worth it.at least you get out and about that way.most if not 18.30s 20s hols you can do yourself.but first time i would book a trip if not sure.
like booze boat trips mainly from san an.lots more to see and do but try not to cramp it all in one week.take a day trip and relax say at night,next day chill out and go for it that night.
people on this site will help you more i bet.plus home page as loads of info and club site.
enjoy it.....
