Hi Lizziebeth
There's enough room on the balcony for 2 & a bottle of wine (exactly what we did).
If your fit & able to walk then there's plenty to see.
Walk into old town, nice churches/mosques to see & we also enjoyed people watching especialy the locals.
There's a park, lots of shops, local fish market, a walk up to the kasbah, souk etc.
Look at this site

We went on a trip to Tarroudannt & enjoyed it. I think the village we went to on the local bus was Azazoul, not a lot there but quaint & on the sea front. Locals were painting their fishing boats & their was a main square (where bus pulled up). then across the road was a lovely walk up the hills. This is the type of things we like to do, I'm in my forties & hubby in his late 50's, last year infact.
When we booked it was a quickie through teletext & we got it a lot cheaper (just over £200 each, I think).
