When you are on holiday, it does not mean that you should stop being yourself. In fact, being on holiday with your girlfriend means that you will be spending all your time with her so she will have more opportunity to get mad with you if you step out of line. There are some things that you can do, however, that should keep her happy. This will allow you to enjoy your trip to Amsterdam without getting into too much trouble.
The first thing that you can do to avoid a fight is to let her choose where you be staying. There is quite a wide range of places that you could stay in Amsterdam, so you will be spoiled for choice. You can let your girlfriend choose all on her own, but then you run the risk of her saying that you did not put any effort into it. If you choose by yourself, then she will feel left out. The key to success is finding the right balance. If you source a few hotels that you think will do the trick, and then let her choose, then she will have it in her mind that she was the decision-maker. There are a few good points to this. Firstly, you will keep her happy. Secondly, you will be staying in a place that you are comfortable with.
Now that you have the accommodation sorted, you have to think about where you would like to eat. Keep in mind that you will be eating at least three times a day if not more so you will have a lot of pleasing to do. Luckily for you Amsterdam is tremendously cosmopolitan so finding food that you both like to eat will not be that hard. If your other half is a vegetarian then try not to take her to the back room of a butchery because you feel like a rare steak. Just use common sense and everything will go smoothly. Nobody knows her better than you, so its up to you to just remember what she likes.
If you manage to keep the peace with regards to food and accommodation, then the rest of your holiday will be a breeze. Keep the details in mind when you are out on the town. Amsterdam has a great nightlife, so when you find yourself in a nightclub try not to make it too obvious when you are ogling the other girls. Always make sure you give your girlfriend all the attention she needs, open doors to restaurants and cabs for her and never let her think you are only buying yourself a drink and not for her. If you stick to the basics, then you will wake up every morning in your hotel room bed looking forward to another day of great fun and games in Amsterdam.
