What do you consider "fun?" History? Art? Music? Food? Hikes? Bikes? Sports? Night clubs? Strip clubs? Remember, we don't know you, and what we like may be what you hate.
How far are you willing to go? xHouston? xGalveston? xAustin?
And let's just be clear, will you have a car?

Take a joyride to Galveston and enjoy the beaches and architecture.

So, I just went to try to look up Magnolia, TX on Google Maps. Looking at the satellite map and looking at the Google Street View, I couldn't find anything that looked like a nice main street. You should check out the street view though, maybe I missed something.

Might I ask why you want to go to Old Town Springs or Magnolia? Magnolia is a mostly dead exurb that people pass through en route from the N. Houston burbs to Austin (via FM 1488). Much of the land around it has been annexed by the Woodlands, which is the soulless burbclave where I grew up. Nothing good in N. Houston.

Old Town Springs is full of overpriced antique shops and schmaltz. If you are into antiques and kitsch, I would strongly consider Galveston, which in light traffic is a one-hour drive south of downtown. There you would get additional benefits of nice architecture, great seafood, and the beach. There are plenty of nice neighborhoods to walk around. You might consider staying at a B&B, or at the Moody Gardens Hotel which has cheap off-season rooms and a beautiful large outdoor swimming pool.

If you are looking for thrift shopping with your antiques in a neighborhood with a younger crowd, I would consider the Montrose and Heights neighborhoods.

Vinnnn clearly has never eaten Japanese food at Uchi, attended a HGO opera production, had a drink at Anvil, or visited the Menil collection. Houston is awesome.
