Our family of four (kids are boy/girl twins, age 14) will be in Colorado from very late at night 4/3 - 4/14. Our son is competing in the Junior Olympics in Colorado Springs so we already have a rental property secured there from 4/7 - 4/14. We are trying to decide on a destination for our first few days before we head to Colorado Springs. We will arrive at DIA very late at night on 4/3 (or possibly very early a.m on 4/4 depending on travel delays) and by the time we get our luggage and rental car we are figuring our best bet would just be to grab a VERY cheap hotel in the Denver area. So that leaves us with the nights of 4/4, 4/5 and 4/6. We were thinking possibly Boulder or maybe Estes Park. Wherever we end up, we will need a rental with a kitchen since our son has food allergies that make restaurant dining more difficult than it's worth (although we would like to find a restaurant or two that can accommodate us so we're not having to cook every single meal while on vacation).
Boulder vacation rentals are a bit pricier than we would like (trying to keep it to $140 or less per night if at all possible for a 2 or 3 BR / 1.5 or 2 BA property). We are open to driving a bit since we'll have a car, and since we're not all that familiar with the area we're open to any and all suggestions. We are not interested in snow activities, but would be interested in learning about the history of the area, art, museums, science, nice shops and that sort of thing.
Any suggestions would be very appreciated. Thanks very much!
