Travel Insurance: If you can’t afford Travel Insurance you can’t afford to travel. It is a no-brainer as far as I am concerned, you have to have it.
Entry into Indonesia is on condition that you have at least 6 months still valid on your passport until expiry. I know of people that have been turned back, a holiday ruined. Check and check again! Visas are not required for stays under 30 days.
Insect Repellent: Mosquitos are an annoying buzzing in my ear, when I am dozing off to sleep. They don’t bite me, but they bite most so come prepared. “OFF” is a favourite in my family.
Currency: The Indonesian Rupiah (roo-pear) has been pretty stable against the New Zealand dollar for the last couple of years, at around 9400 Rupiah to the dollar. NZ Currency can be easily exchanged but it is best to have it in large denominations ($50/$100) as it is a better exchange rate. This is true for all currencies. You can also take credit and debit cards, as ATM machines are available in all the main tourist areas. The large Department stores and many well-known restaurants also take credit cards. Check with your bank as to how much they charge for cash withdrawals.
Weather: Bali maintains a consistent heat of 27-29, with the humidity reaching its highest between January and April at 80%. The rainy season is November through to March, the dry season April to October. May is considered the warmest month. Inland can be cooler, but for visiting New Zealanders on a short holiday not climatized to the weather, the drop in temperature is just a welcome relief, with no need for additional clothing.
Mobile Phones: All NZ mobile providers have different charges and packages available for mobile roaming in Indonesia. If you can remove your SIM then you can have an Indonesian SIM card, which attracts far cheaper rates. We can arrange this for you in Bali. If you are in a locked plan with your provider and are needing a lot of contact with New Zealand, then your best option is to buy a cheap phone and get an Indonesian SIM card.
Water: You cannot drink the tap water in Bali. You must clean your teeth with bottled water. The Hotel supplies bottled water daily to your room, along with a thermos of boiled water. Cheap bottled water is plentiful throughout Bali.
Bali Belly: Living life no matter where you are or what you are doing, there will be times that things are not always that great. The one thing that could occur on your holiday - and the chances are in a group of ten people are quite high - is Bali Belly.
After suffering from this, from the mild (needing to rush to the toilet) to the extreme (intense stomach cramps and not getting off the toilet for days), I can tell you that Imodium is the only medicine out there that works. I have tried all sorts of supposed cures, from charcoal tablets to rice porridge, and nothing other than Imodium helps. I would definitely encourage you to bring a packet with you.
I am not a doctor, and am only relating my experiences. If you are at all concerned, please see your doctor, or talk to a pharmacist, as it is over-the-counter medication.
