To be honest, it's probably not a good sector to get into in the current economic climate. People are really cutting back on holidays at the moment, and travel companies are therefore cutting back on staff.
The retail sector is also diabolical at the moment; so many companies are struggling financially, that there are very few retail jobs going (and also bear in mind that there are now thousands of ex-Woolworths, Zavvi, Adams and MFI employees looking for work too).
If you've got good IT skills and fancy doing something in the admin line, then I'd say follow that route. If you get a general administrative role then it would give you a chance to find out what parts of office work you particularly enjoy, and you could then work your way up. The majority of companies looking for good administrative personnel want experience above qualifications. If you want to go to college one night a week, then maybe doing the ECDL or some typing qualifications would help you career-wise.
Alternatively, you could follow the childcare route. People will always need good childminders, and if that appeals to you then go for it. Visit the National Childminding Association's website:-
http://www.ncma.org.uk/ for more information and advice about the process. I believe there is a setting-up grant available to people wishing to become childminders, although these schemes do vary regionally.
Good luck, whatever you decide to do!
