I remember approximately 3. I know there was one by the table and chairs, and one by the bathroom sink, and I think at least one more somewhere else.
Bring a surge protector because then all your electronics will be in one place. That helps alot.
Thanks everyone! It's just me going solo and I'll have like, iPhone, iPad to charge up every night and then my 3DS and camera and portable iPhone charger to charge every other night/in the day, so I think I'll be alright!
Last time i went with my mum, sister, brother and niece and there were a few heated discussions about who got the sockets nearest the beds, so next family trip I'll be using your ideas!
