Just been re-reading through this thread and had a few thoughts about how we're going to be doing our trip next January.
1. We usually stay in moderates but the reality is we are seldom at the resort other than to sleep, so this trip we're going to stay in a (gasp), value, specifically POP. I'm going to make a number of equal payments, monthly and hopefully even out some of the exchange-rate pain.
2. We are going to order water and a bunch of snacks/fruit/breakfast items from Garden Grocer and take a bag to the parks with us each day. Order early and you get a discount. Will still "need" a Mickey bar now and then.
3. We also have been fans of the free dining offers over the years, but really with the tips for TS and all those desserts we are probably better off (financially and nutritionally) without a meal plan and just pay out of pocket for food. We've found quite a few CS meals that DW and I can easily share for lunch and be quite satisfied. Think Flametree BBQ. And no drinks, we'll bring our own water. We do have our favourite sit down restaurants but we don't need a TS every day by any means. Probably will still do two or even three TS meals while there.
4. We are a few hours driving time away from our nearest airport (YEG) so we're going to choose our flights carefully to avoid having to spend a night at the airport hotel for at least one direction of travel. I'd rather pay $100 more on flights than $300 on hotel stays.
5. While trying to be frugal with this trip, I'm not about to turn it into a cost analysis exercise. It is a vacation after all. If we're stressing over money the whole time, why bother? I'll be careful about the money while planning but I fully intend to forget about it while we're there.
Anyway, that's my 2 bits worth.
