1.What’s your tent budget?
2. Where you going with it? #
3. Just the two of you + kit + somewhere dry to sit?
4. Weight capacity?
5. Tarp?
6. Standing room or happy crouching? ( #2 dependant )
7. Snug or roomy?
8. Tunnel, dome or teepee?
9. Pack size?
#2 & 6…… if you’re going somewhere that could be exposed / stormy then you really don’t want a tent tall enough to stand in because it will get battered / broken in high winds and rain. A lower stronger tent would be needed. Saying that, a good, strong, high quality teepee tent, that’s tall enough to stand in can be exceptionally good in high winds. They are very easy to put up but there’s usually a weight penalty and not easy to add a tarp to.
I would definitely recommend a Hilleberg ( I have 4!

) but they’re blooming expensive but will withstand nearly everything nature can throw at them.
The bike garage type tents that you can stand up in are great in mostly calm conditions but throw some decent wind at them and they can become an issue. Trust me, I’ve had the 2 main types you can get. Unless you add extra guy lines to them then you’ll have problems in high blustery winds. Before those that have them start spitting dummies out I did say in most calm / light winds they are great.
Budget is the biggest thing. Buy the best you can afford. If you buy a Hilleberg, for example then you will always get the majority of your money back when you come to sell it in a few years. They tend to hold their price because of the quality.
Give us a bit more info and we can narrow the choice down a bit.
What other kit do you already have? Airbeds, lights, cooking equipment, sleeping bags etc……
DON’T skimp on good quality airbeds either. They can make a MASSIVE difference as to whether you have a good nights sleep or not. Having a crap air bed can ruin a holiday. Also I’d definitely recommend NOT having a double airbed. Get two singles.
