We're off to Barcelona next week to Mobile World Congress 2015 (MWC) and that might sound like the best thing ever to you but it's not all fun and games.

Not everything's bad, of course. We get to try out the coolest new tech, and we'll be bringing you everything you need to know about the brand-new smartphones, tablets, wearables and other gadgets that are being unveiled and shown off on the show floor. We're expecting to get our first look at the Samsung Galaxy S6, HTC One M9 and much more.

But there are some things that are not so great, so here's the side of MWC you don't normally see (unless you're also a journalist, of course). Here are five things we hate about MWC to give you an idea of what it's like to be a journalist at a technology trade show.

5 things we hate about MWC: Everything is miles away

We're used to sitting at desks on comfortable chairs typing away while listening to music. So, walking around a huge show isn't something our legs are used to. MWC is one of the smaller shows on the calendar but that doesn't mean it's small. Each hall, of which there are eight, is bigger than the football pitch and is full of stands from different tech manufacturers. This means everything can be literally miles away and it's pretty easy to get lost trying to find a specific stand. All of this and you've got to carry a mobile office on your back. Ouch.

5 things we hate about MWC: Food

Not unique to MWC, but we tend to end up malnourished at trade shows. The food is foreign, which can be good but also regrettably bad, and your eating times inevitably get screwed up (there's just so much to see and do! No time for eating) and it's made worse by the exceptionally long queues. CES, in Las Vegas is not so bad for food, mostly because there is a press packed lunch served every day but no such joy in Barcelona. 

5 things we hate about MWC: Queues

We're English, so we're naturally good at queuing – or so the saying goes. The queues are MWC are nothing short of horrific. No matter what you're trying to do or where you're trying to go, there will be a gigantic queue.

As we already mentioned there are out-the-door queues for food at lunch time, picking up your badge to get you into the show, queues as far as the eye can see for taxis at the end of the day and queues to see devices on stands which everyone wants to get hands-on with (except the rubbish products). And you'll need to know well in advance when you need to pee, because you've probably got a got 30 minute wait before you can get anywhere near the restrooms.

5 things we hate about MWC: Wi-Fi

In order to bring you all the information we're gathering at great speed while pacing round the show, we need a good internet connection. Unfortunately, as with almost every other show and press event, the Wi-Fi is unreliable. Obviously it's going to be difficult to provide a speedy and constant connection to thousands of attendees but nevertheless it doesn't half make our job frustrating. Luckily the press room has hard wired ethernet cables so it's not all bad. Though that's if you manage to nab yourself a table squeezed between the other hot and bothered journalists and their many gadgets.

5 things we hate about MWC: Expenses

Ok so this is most definitely a first world problem but expensing a trip like MWC is an absolute nightmare. Remembering to get a receipt for everything you buy is hard enough, not losing said receipts is even harder to accomplish. If you manage to do all that, there's the task of sorting through it all when you're finally back in the office. As the photo shows, this is a pretty tricky, not only logistically but also working out what the items are since the receipts are in Spanish.
