Agree with checking out Uncle Ho, but make sure that he's in residence. Apparently, they send him back to Russia for periodic maintenance... something like once a year in the fall as I recall. The mausoleum isn't available for perusal. They just march you through in a line, up the stairs, through the halls, past Ho, and then out the back into the gardens. In front of the mausoleum is a massive parade area with a huge field behind. Great for wandering, reflection, photography, etc.

ka9taw, what did you think of the pottery villiage? I found it to be a bit over-rated. The workmanship didn't seem all that great, and most was rather 'kitschy' (if that is a word). Since the 'villiage' was really only one block long, it was easy to walk out into the countryside and get a good look-see, which was very enjoyable and informative.

I always get my Vietnam visas in Bangkok in one day. The embassy is on Wireless Rd (Thanon Wittayu) just north of the US Embassy. As you drop off your PP and application, request an 'express visa.' You will pay a bit extra, but it will be available for pickup in the afternoon.
