I’ve noticed that the 2015 “Rally with a Chalet” is being advertised. It’s a cracking event, but be advised that single accommodation is - as far as I know - virtually non-existent. (I stand ready to be corrected if this is not the case.) So be prepared to share if you want maximum VFM.                                                                                                                                                                             

As this is based at Pontins you are correct as holiday park accomodation does not usually cater for single occupnacy.
  But its still great value for money anyway :)                                                                                                                                                                             

The accommodation is not expensive I ususlly go on my own and it cost me £52 for a chalet I have to pay for two people even for being on my own. Great weekend worth every penny                                                                                                                                                                              

You're only right, CG. That's what I've done over the past two years - I've booked a twin chalet for myself over the three days. The only (slight) problem has been on arrival, when the security guard at the gate (and they've been quite friendly) asks me where the other person alluded to on the documentation is, and I tell them they're "not coming". And I get a brief, sympathetic glance, as though I've been dumped by someone... who doesn't exist...                                                                                                                                                                              

Valencia, I have never been questioned.                                                                                                                                                                              

You must look less suspicious than me, CG. There again, most people do.
