I don't mean to be rude but are you aiming at the right level of job at the moment? I think the important thing is to get used to the working world again (it's going to be a shock after over 11 years of being able to organise your own time to suddenly find you're following someone else's rules - I've seen this with people who've only taken a couple of years off). Is there any sort of careers advisory service in a job centre near you? They could really help you to see what sort of job you should be aiming for to give you the right experience to move towards hospitality or event management
Think about how you can build up your cv and gain experience while looking for work. Have you helped out with events at school, sports days, jumble sales etc? It can all be worded in a way to help when looking for work. Have a think about voluntary work - volunteers help with everything from charity shops through to admin etc and most charities are pleased to be contacted. Try contacting your local FE college - you may find they have some free courses that could get you up to date with skills you'll need in the work place (a certificate in some sort of IT literacy, hygiene certs for catering etc that a potential employer can take as evidence of your ability).
Good luck - age shouldn't be a barrier (you don't actually have to put your date of birth on a cv these days due to legislation changes).
