I think it's great advice to be wary of all these things when going to Benidorm. And for any holiday resort for that matter, although I appreciate that the issues might not be as bad in other places.
However, I would add that the vast majority of people have a great time in Benidorm free of any hassle. It's not just about the main strip either. There's something for everyone and there are some very nice parts to it. The old town is lovely. Where I was staying for the Villarreal match was on the other side of Benidorm to where the old town is but a good 20 or so minutes walk away from the main strip so it was pretty chilled. The hotel I was in was mint and very reasonably priced considering I was a solo traveller staying in a double room. Sure, I went down to the strip on Monday night and did a few hours in the Red Lion with
@Indaparkside and hundreds of other blues but I made sure I didn't hammer the drinking too much (which makes a change for me!) as I didn't fancy staggering out of there at 5 in the morning and barely knowing where I was. Got out of there at around 2.30am, grabbed a kebab, and jumped a taxi back to my hotel. For all the bad reports about the place and certain bars, the taxis have a generally good reputation for being safe so I'd recommend using them instead of walking back to your gaff. That said, I didn't do that on Tuesday when the coach dropped me off near the strip after the match. I walked back after having a couple of pints in the Silver Dollar pub with a few other City and buying the obligatory kebab but again, I wasn't wankered. And the street that my hotel was on was just round the corner from there so it was pretty much a straight walk up.
