Tip #1: I still use a Garmin nuvi and will bring it with me on trips. When I'm putting together plans for a trip I will throw various addresses into a spreadsheet and then a week or so before I leave I will load them into the GPS. Saves time while away and also I'll occasionally find out that I have a street name wrong or a street number that I have doesn't exist. We do a lot of repeat travels, so once I have them entered as favorites they will be there for future trips.
Tip #2: Always recheck hotel and rental car rates. I find that more than 50% of the time I can find a lower rate after the initial booking.
Tip#3: Throw a winter hat into your golf bag, even when traveling to a "warm" weather destination.
