Some thoughts, mostly in response to Will's
post number 52 (and I know there have been subsequent comments). I'm not planning to join the crawl, so make of my comments what you will. I could meet after work, though, if the group is still going (and reasonably coherent).
The most obvious thought is that you have a three pubs out on a bit of a limb from the rest. The first is
Brighton Beer Dispensary. I can see why this is on the list, but it does take you a fair way to the west. I see a return via
The Lion and Lobster has been suggested, but that's taking you further west still. Perhaps
The Royal Sovereign would be an alternative? You could take a chance on
The Tempest or
Fortune of War on Kings Road Arches (or just walk on by).
I would, in any case, recommend that you try to avoid heading directly along Western Road and North Street, as these are the main shopping roads, as well as the route of all the cross-town buses. On a Friday, it's going to be pretty busy!
On the other side of town, you've picked both
The Southover and
The Hanover. These are Indigo Pubs - a good local operator, don't get me wrong. Each of their pubs tries to come up with a slightly different offering, but there are enough similarities for you to possibly be thinking "isn't this quite a lot like the last pub we were in?". Not only that, but Southover Street itself is a steep old climb which some of the group may not appreciate. I'd be inclined to stick to the lower slopes of Hanover on a crawl of this length. If you are visiting
The Geese Have Gone Over The Water, some of you might also like to drop in on
The Greys across the road which is currently under threat of closure. It may be gone by the time you get there but it could also be a "last chance to see". If you're then heading to (or from)
The Admiral (a new one on me, so thanks for the tip-off), both
The Village and
The Reservoir look interesting, with a bit of money spent recently.
Lastly, as far as the crawl goes, is the consideration of where to finish - the last few pubs at least, since it'll be a Friday night, with Easter approaching and the last day of University term, it's likely to be busy.
The North Laine is pretty big and does attract quite a crowd (which is good), but also gets pretty loud inside (which is not so good).
The Lord Nelson (a Harveys pub, with about 6 from the range on the pumps) usually has a fair amount of room inside, and
The Prince Albert a few doors up, not so much.
A couple more you might consider:
The Independent (more Queen's Park than Hanover) and
Brighton Bierhaus, on the edge of Kemp Town.
For those staying a little longer, you might want to venture a little further afield. If it's micropubs you're after, there's
The Watchmakers in Hove (a superior example of the genre, up there with The Brooksteed and One In The Wood) and
The Old Star in Shoreham (just following the standard formula in my view). Also in Shoreham is
The Wellington, run by Rob Jones formerly of Dark Star Brewery (but still no brewing on site, I believe).
The Westbourne between Hove and Portslade always seems to get good reviews. In Portslade itself,
The Railway Inn (note name change) has had a recent makeover and, back in Brighton and near to the station (though uphill!),
The West Hill has also changed hands not so long ago (with 'big plans' from the new owners).
Out east, the only one that springs to mind is
The Bevy, notable as being the first community-run estate pub. Fortunately, there's a bus stop outside, so no need to be wandering the local streets late at night.
Talking of which, local buses are mostly fairly high-quality and high-frequency though also high-fare, without a bit of forward planning. Local trains are by Southern.
Hope you enjoy your day - as I said quite a few paragraphs back, I may be able to join you for the evening.
