I can really 'Big Up' the Sun holidays, me and my family have been on 4 so far and they are fab! You go to Haven camps, so there is plenty to do for kids and adults, you can upgrade if you want to, we have upgraded to a Rory tiger caravan which the kids loved. You stay in the same caravan as people who have paid top dollar for their holiday!
Our next door neighbours have just gone to Hafan-y-Mor, North Wales for a week and paid £750!!!!!! We went for a week and it cost us £95 for a family of 4 and we upgraded!! Bargain!!
