Hi Pat
I can help with some of your questions - hopefully other readers will offer some suggestions about the rest!
Currency: £1 = about 110 Kenyan Shillings
Spending money: It's difficult to say, as you could get by without spending very much or you could spend wildly! It's worth bearing in mind that there are a few optional excursions, which you may decide to do.
- Half Day city tour of Mombasa (about £33)
- Full Day trip to Tamarind & Haller Park (about £72)
- Dolphin Dhow trip (about £87)
Vaccinations: You should talk to your GP or NHS Direct about this subject, as they will know much more about the subject than I do! However, a good starting point is to visit the NHS website at www.fitfortravel.nhs.uk.
Humidity: This isn't as much of an issue in Kenya as you might expect. You'll probably find it a little higher near the coast, although the sea breezes help reduce the effect.
Manchester-Heathrow flights: BA and bmi are your best bets for connecting flights. Have a look at their websites for the latest fares.
I hope this helps.
Kind regards,
Olly, your editor
