Why is it so difficult for travel agents to find reasonably priced overseas holidays which have children's clubs/activities and which does not involve the booking of 2 separate rooms or the need to sit in the travel agent whilst they call several hotels to see if the room/suite/apartment actually will hold 5 people?
Is it so unusual to have a family consisting of 2 adults and 3 children (aged 4, 7 & 12)? 
Any tips on good travel agents or holidays for a family of 5 would be great. :)
