2 Plan in advance

Why? So that you have memories to share and don't have to bother planning your agenda when you get there (this often leads to you never going anywhere). Forward planning also means you avoid those dreaded "What shall we do today?" conversations that can so easily turn into arguments! 

How? The secret to striking the right balance between too much and too little preparation is to make a rough plan of what you're going to do (explore the place one day, SCUBA dive the next, sunbathe, sightsee, hit the beach etc) but leave yourself enough flexibility to be able to change your plans according to your whims. Don't forget that the spur of the moment often provides the most fun!  

Many couples are so scared they'll run out of things to say to each other on holiday that they fill their time with too many different activities. "You'll come back tired without having made the most of the space you had to build on your relationship," says our expert. "Don't worry about getting bored. Time spent doing nothing and saying nothing are part and parcel of relaxing on holiday."
