I've done quite a few long journeys of up to 220 miles in one stint, knowing that I'll be charging overnight at the destination using either 13amp or 32amp. But as a backup I usually work out where the nearest 32amp or 70amp sites are … just in case. I've only ever needed a mid-journey top up on half a dozen occaisions. There are numerous websites for this, such as from :-
Home - Zero Carbon World
The 32amp / blue commando outlets can only be used if you've purchased a UMC cable from Tesla or made one up somehow. These charge up at the rate of about 25+ miles an hour.
The 70amp HPC chargers all have a dedicated cable attached, so you pitch up and plug in. They recharge the battery at about 60 miles an hour of charge (depends on your watts / mile usage).
I've often used the HPC located at the Castle Hotel, Taunton, M5. I've rolled up, plugged in and gone and had a meal in their restaurant.
The other HPC I've used a couple of times is at the Nottingham Belfry, just off J28 on the M1. But they tend to lock the box its attached to, although the receptionist will give you a key, and they've got a bar/restaurant right opposite the entrance.
If a charge point mid journey is critical, then I suggest calling beforehand just to make sure its all working....
Also, whilst I haven't yet done this, Ecotricity are gradually rolling out 32amp Mennekes charge points at all Welcome-Break motorway service stations, but you need to get the Mennekes adapter for this, and check the website for which locations have been commisioned - although I've seen some posts on the Leaftalk forum about 2 sites which appear to have had some teething problems.
If you're going to do some really long journeys get familiar with Range-Mode, and how the Estimated and Ideal range indications behave. One thing to bear in mind is to resist doing 95+mph up a motorway ... as the range will drop significantly to something like 120-140miles. If you want to maximise the distance just take it easy on the accelerator and do 60-70 on a motorway, or better still move with the traffic on major A roads where the average speed is more like 50-60mph, and if things are getting critical - go a bit slower !
Many UK owners have written up their first long journey, and the links below should provide a good insight as how they got on :-

A weekend in the English Lake District with a Roadster, UK HPC, Zero:Net, and OVMS
A Very British Road Trip (or 2010 Roadster Sport: A Space Odyssey, if you prefer))

Good luck with your first trip, and write it up when you get back !

. The only slight drama was a power cut at our B&B accommodation on the morning we were leaving, which prevented us topping up.
... we made it back without being electrocuted, or sterilised by magnetic fields, and the Tesla behaved impeccably as always
