Guild Wars is fun if you're into PvP. It's really well-designed and balanced in that regard. There's a decent amount of PvE content but nothing that'll keep you up all night playing like EQ2. OTOH, GW is great if you need a game you can play for an hour, get somewhere, then log off. Unfortunately, there isn't an all-in-one package for GW like there is for usual MMORPGs so it'd be $30 for the base game, $40 for Factions, $50 for Nightfall, $40 for Eye of the North.... cut out $10 from that if you get the bundle of the base game and EotN. Still $150 total per account just to have the game and all the expansions, which is ~5mo EQ2 sub time... OTOH you can live w/o the newest expansions (unlike EQ2), but it makes PvP a bit tougher to compete in (albeit nothing insane).
Though, honestly, $30/mo ($15/ea x2) isn't a very high price for the amount of time you can invest into an MMORPG. One month for two accounts is cheaper than seeing a movie after food/drink costs
At the very least make sure you don't completely kill your entertainment budget or dealing with a baby will be unbearable.
Oh, and once you've played good pay-to-play MMORPGs, the free-to-play ones are total suckage
