spider and vacation

I have a rose hair tarantula. It's winter break and I'm staying at my parents house 2 hours away from my house. I offered crickets before I left but she didn't eat. I left on the 16th. I drove back up on the 23/24 to do some errands and fill her water. I have to go up on the 8th to do stuff and it kinda sucks to drive up 2 hours to fill a water bowl I'm not even sure she really needs. But I'm so nervous about it because she didn't eat so she didn't get water that way. Do you guys think I should go back? on the 3rd? to fill her water and then I could go on the 9th and then I'd be home for good on the 15th. Also there is 2 weeks total until I go home and right now she hasn't eaten for 3 weeks. It's possible that she could molt since she hasn't in a year and a half but she doesn't really look pre molt. Should I feed her when I go back on the 3rd or 9th and if she doesn't eat within a few hours take the crickets out?

She'll be fine, trust me. And yes, it's very possible that she's going to molt. I've had a few that just stopped eating, but never got a bald patch and then out of nowhere molted, they don't always get that premolt look.

If you're really worried about her water, then if you're in the area by all means go a refill it, but if you don't end up in the area she'll be perfectly fine for a little bit. And I wouldn't bother trying to feed her. If she's been refusing for three weeks, just wait until she molts or at least give her another couple weeks.
