costa rica national parks

Where should we go for our 25th wedding anniversary?
It is in mid-April, hubby is from costa rica and loves the warmer weather, I on the other hand am from Kentucky and hate summer and sunshine and am allergic to the sun and love the snow! I am also mobility challenged and can’t walk far distances because of my disability. We are looking for somewhere outside the USA that is a cheap flight and fairly cheap room and board. My dream is Bermuda(at night! out of the sun), but it’s so expensive. We’ve been all over the USA so isn’t much left here to see, but you are welcome to suggest a place here in the USA, we’ve already hit Yellowstone and all the other national parks, Hollywood, Dollywood, etc. Any ideas would be appreciated.
Barbados!

If you want to stay out of the sun, you can always do the sightseeings, shopping, or go swimming.
