When traveling, laundry can be a challenge and a costly affair if one were to use the laundry services offered by hotels. An alternative to washing your underwear in the wash basin, is to put them all in a zipper net laundry bag of the type used for washing push ups, and ask if the hotel laundry service can accept that bag as one item (instead of charging per piece of underwear, resulting in a hefty bill). The laundry bags are also useful for separating dirty underwear from clean ones in your luggage.

When travelling, shirts can be rather creased and rumpled when you unpack them from your case. In your hotel room, when the shower is still hot and steamy, hang up your creased shirt on a hanger in the shower recess, and the hot moist air will help get the wrinkles out.

If staying in a hostel take plenty of cloth bags for wet/dirty washing and to keep items seperate in. They are not waterproof like plastic bags, but as well as being better for the environment, you will save a lot of unhappy fellow travellers complaining about the scrunching plastic bag noises as you try to dress and organise luggage very early/late!

For single traveller: when entering washroom with wet/ less hygenic floor, often we face problem of handling our luggage. Always standby newspaper/ plastic cover sheet in our luggage and place it on the floor. This can prevent our belongings from getting dirty or wet. Dispose after use if necessary.

When traveling be sure to pack copies of your itinerary (with travel agents info), passport, and credit cards in each suitcase including your carry ons. This will insure that if anything is lost or stolen that you call call and check on it and that the airlines will know where you are.

Always bring enough memory cards for your digital camera when traveling in Egypt. You will not be able to find a CD burner in all the Internet cafes to enable you to download your beautiful pictures ...To add to your surprise, even hotels do not provide such a facility... We (I and my friend) did not opt for printing the pictures as we had not much time (The tour group could not afford to wait for us). We found a photo printing shop and pleaded to help to burn all the pictures...And this costed us USD 25! This really burned holes in our pockets...We learned that the CD burners were banned in all local shops (even in the computer shops) as a way to eradicate pirated CD products. We learned the lessons the hard way...From that time onwards, we always remember to set the size of the image before we take any pictures using our digital camera...Sob~ Sob~

Expensive meals inside Tioman Island? I found a place with Malaysian meals (they’re called mamak stalls), with rice, chicken, etc. A clean small stall. Just walk further down the resort, at the far end where you see some low cost apartments after you’ve past the ponies farm, on the right hand side after the guard house gate. If you intend to stay long, why not opt for a cheaper meal?

When in Oslo, be sure to take a guided tour of the castle on the waterfront. For a small fee you'll get to take in the whole history of Norway, access to special castle areas and insights into the Norwegian way of thinking from some very nice tour guides. Example of trivia: 2005 will mark the first 100 years of modern Norway. So, next year will be party, party!! Bonus tip: in the lee of the castle is an excellent museum of Norway’s experience of WWII. You could spend a day doing both museum tours or packing them into 2 hours like I did.

Bali has many beautiful beaches, that's already known. But have you ever try Bangka and Belitung Islands? They have many "pure" and "natural" beaches, and cheaper prices.
