if your on the west coast (or there abouts)
consider
Sonoma Mission Inn - very romantic, great spa, visit the wine country (sonoma valley)
Post Ranch Inn (if you have the cash), or The Ventana Inn (Big Sur - also not cheap, but worth it) - UBER romantic..try to get a cabin at the Ventana Inn, it has it's own private terrace/jacuzzi, fireplace in bedroom
you can get a package deal for 3-4 days, airfare and hotel and all meals and drinks to Cancun - real bargin and quite nice
if your on the ast coast - look for some incredible deals right now on airfare to London - probably some package deals that are cheap - transatlantic airfares are down right now (don't know about april)
if your in the midwest- think about florida - sarasota is really nice
toronto is also an easy "foreign" destination to go to for cheap ... you may want to get passport applications made if you don't have'em just in case you go abroad.
